Package Structure

A PresentationML or .pptx file is a zip file (a package) containing a number of "parts" (typically UTF-8 or UTF-16 encoded) or XML files. The package may also contain other media files such as images. The structure is organized according to the Open Packaging Conventions as outlined in Part 2 of the OOXML standard ECMA-376.

The number and types of parts will vary based on what is in the presentation, but there will always be a [Content_Types].xml, one or more relationship (.rels) parts, and a presentation part (presentation.xml), which is located within the ppt folder for Microsoft Powerpoint files. Typically there will also be at least one slide part, together with a master slide and a layout slide from which the slide is formed.

Content Types

Every package must have a [Content_Types].xml, found at the root of the package. This file contains a list of all of the content types of the parts in the package. Every part and its type must be listed in [Content_Types].xml. The following is a content type for a slide part:

<Override PartName="/ppt/slides/slide1.xml" ContentType="application/vnd.openxmlformats-officedocument.presentationml.slide+xml"/>

When adding new parts to the package, it is important to keep in mind that not only must you add the new part and update any relationships within .rels files, but also the Content_Types.xml file must be updated.

Relationships

Every package contains a relationships part that defines the relationships between the other parts and to resources outside of the package. This separates the relationships from content and makes it easy to change relationships without changing the sources that reference targets.

For an OOXML package, there is always a relationships part (.rels) within the _rels folder that identifies the starting parts of the package, or the package relationships. For example, the following defines the identity of the start part for the content of a presentation:

<Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="ppt/presentation.xml"/> .

There are also typically relationships within .rels for app.xml and core.xml.

In addition to the relationships part for the package, each part that is the source of one or more relationships will have its own relationships part. Each such relationship part is found within a _rels sub-folder of the part and is named by appending '.rels' to the name of the part.

Typically the main content part (presentation.xml) has its own relationships part (presentation.xml.rels). It will contain relationships to the other parts of the content, such as slideMaster1.xml, notesMaster1.xml, handoutMaster1.xml, slide1.xml, presProps.xml, tableStyles.xml, theme1.xml, as well as the URIs for external links.

A relationship can be either explicit or implicit. For an explicit relationship, a resource is referenced using the Id attribute of a <Relationship> element. That is, the Id in the source maps directly to an Id of a relationship item, with an explicit reference to the target.

For example, a slide might contain a hyperlink such as this:

The r:id="rId2" references the following relationship within the relationships part for the slide (slide1.xml.rels).

For an implicit relationship, there is no such direct reference to a <Relationship> Id . Instead, the reference is understood.

Parts Specific to PresentationML Documents

Below is a list of the possible parts of a PresentationML package that are specific to PresentationML presentations. Keep in mind that a presentation may only have a few of these parts. For example, if a presentation has no notes, then a notes master part will not be included in the package.

Parts Shared by Other OOXML Documents

There are a number of part types that may appear in any OOXML package. Below are some of the more relevant parts for PresentationML documents.

Understanding openxml for powerpoint presentations.

Creating cool Mocrosoft PowerPoint (PPT/PPTX) presentations means understanding the tools behind them. One key tool is OpenXML SDK , which helps make slideshows. This article explains how OpenXML SDK works with PowerPoint, so it's easier to understand.

The Power of OpenXML API

OpenXML provides a powerful slides API for working with PowerPoint presentations in .NET applications. It allows developers to programmatically create, modify, and customize slides, layouts, and formatting. The API exposes a range of functionalities that enable precise control over the elements within a presentation.

Usage of API for Presentation Creation

To create a presentation using the OpenXML SDK, developers typically follow these steps:

Initialize a Presentation Document: Start by creating a new presentation document.

Add Slides and Content: Utilize the API to add slides, set layouts, and add content such as text, images, and shapes.

Customize Formatting: Adjust formatting options such as fonts, colors, and styles to meet specific design requirements.

Save and Close: Save the changes made to the presentation and close the document.

Complexity Compared to Other APIs

OpenXML SDK gives you a lot of control and flexibility, but it's known for being complex, especially compared to easier-to-use APIs. Here's why:

Detailed Control: OpenXML lets you control every little detail of your documents. This can be overwhelming for developers who prefer simpler options.

Learning Challenge: Because it's so detailed, you need to understand the inner workings of XML documents to master OpenXML. This can be harder to learn compared to simpler APIs.

Lots of Code: Using OpenXML often means writing a lot of code, even for basic tasks. This can make your code harder to understand and maintain.

Precise, but Not Always Quick: While OpenXML gives you precise control, it might not be the fastest or easiest option. Some other APIs offer simpler solutions for common tasks.

So, while OpenXML gives you amazing control over PowerPoint presentations, it might come with a learning curve. Developers need to decide if the precision and detail are worth the extra effort, or if they'd prefer a simpler approach for their projects.

What is a PPTX file?

Files with PPTX extension are presentation files created with popular Microsoft PowerPoint application. Unlike the previous version of presentation file format PPT which was binary, the PPTX format is based on the Microsoft PowerPoint open XML presentation file format. A presentation file is a collection of slides where each slide can comprise of text, images, formatting, animations, and other media. These slides are presented to audience in the form of slideshows with custom presentation settings.

Brief History

PPTX file format was introduced in 2007 and uses the Open XML standard adapted by Microsoft back in 2000. Previous to PPTX, the common file format used was PPT that was pure binary file format. The new file type has added advantages of small file sizes, less changes of corruption and well formatted images representation. It was in the early 2000 when Microsoft decided to go for the change to accommodate the standard for  Office Open XML . By 2007, this new file format became part of Office 2007 and is carried on in the new versions of Microsoft Office as well.

PPTX File Format Specifications

Files generated with office Open XML file format is a collection of XML files along with other files that provide links between all the constituent files. This collection is actually a compressed archive that can be extracted to view its contents. To do so, just rename the PPTX file extension with zip and extract it for observing its contents (See PPTX file format specifications by Microsoft).

Following sections shed some light on each one of these.

[Content_Types].xml

This is the only file that is found at the base level when the zip is extracted. It lists the content types for parts within the package. All references to the XML files included in the package are referenced in this XML file. Following is a content type for a slide part:

If new parts need to be added to the package, it can be done by adding the new part and update any relationships within the .rels files. It has to be kept in mind that for such a change, the Content_Types.xml must also be updated.

_rels (Folder)

Relationships between the other parts and resources outside of the package are maintained by the relationships part. The Relationships folder contains a single XML file that stores the package-level relationships. Links to the key parts of the PPTX files are contained in this file as URIs. These URIs identify the type of relationship of each key part to the package. This includes the relationship to primary office document located as ppt/presentation.xml and other parts within docProps as core and extended properties.

Each part of document that is the source of one or more relationships will have its own relationships part where each such relationship part is found within a _rels sub-folder of the part and is named by appending ‘.rels’ to the name of the part. The main content part (presentation.xml) has its own relationships part (presentation.xml.rels). It contains relationships to other other parts of the content such as slideMaster1.xml, notesMaster1.xml, handoutMaster1.xml, slide1.xml, presProps.xml, tableStyles.xml, theme1.xml, as well as the URIs for external links.

Explicit Relationship

For an explicit relationship, a resource is referenced using the Id attribute of a  element. That is, the Id in the source maps directly to an Id of a relationship item, with an explicit reference to the target.

For example, a slide might contain a hyperlink such as this:

The r:id#“rId2” references the following relationship within the relationships part for the slide (slide1.xml.rels).

Implicit Relationship

For an implicit relationship, there is no such direct reference to a  <Relationship> Id . Instead, the reference is understood.

This is the main folder that contains all the details about the contents of the Presentation. By default, it has following folders:

• slideLayouts
• slideMasters

and following xml files:

• presentation.xml
• presProps.xml
• tableStyles.xml
• viewProps.xml
• [MS-PPTX] - PPTX File Format
• Open Office XML
• AVIF File Format
• RA File Format
• KT File Format
• RM File Format
• RV File Format

A file with the .pptx  file extension  is a Microsoft PowerPoint Open XML (PPTX) file created by Microsoft PowerPoint. You can also open this type of file with other presentation apps, like OpenOffice Impress, Google Slides, or Apple Keynote. They are stored as a compressed ZIP file, which use a bunch of other files with formatted text, images, videos, and more to open them.

PPTX files are used in Microsoft PowerPoint, a presentation program used to display content in a slideshow format. Each slide can contain graphics, formatted text, videos, music, animations, and more.

First introduced with Microsoft Office 2007 in the Office Open XML standard, PPTX is the default format when creating a presentation using modern versions of PowerPoint. Microsoft introduced this open format largely due to increased competition from Open Office and its Open Document Format (ODF). The PPTX format replaced the proprietary PPT format that PowerPoint used previously.

Because PPTX files have become standardized, you can open them in many applications on different platforms. Although Windows doesn't natively open them unless you have a copy of Microsoft Office 2007---or PowerPoint 2007---or later, you can download a third-party open-source application like  Apache OpenOffice  or  LibreOffice  to open your files.

Mac users only need to double-click the file to have it open up in the Apple Keynote application.

If you'd rather store, open, and edit all your Office Open XML files in the cloud, you can do so by uploading your document via PowerPoint Online  or Google Slides .

Alternatively, if you're a Chrome user, you can download the extension  Office Editing for Docs, Sheets & Slides  (an official Google extension) for your browser. It lets you upload any PPTX file directly from your local hard drive to your Google Drive by dragging and dropping it into any Chrome tab.

• Frequently Asked Questions (FAQ)

Understanding PowerPoint File Formats

It’s possible to use PowerPoint for years without ever thinking about the various file formats that are available to you. By learning about PowerPoint’s file formats and options, however, you can do a much more effective job of creating presentations, backing them up, sharing them with colleagues, and protecting the information that they contain.

Ordinary PowerPoint Presentations

When you save a simple PowerPoint presentation, you give it a name, and PowerPoint adds the file extension .pptx. Your Sales Presentation file becomes Sales Presentation.pptx .

If your PowerPoint presentation contains one or more macros, PowerPoint will automatically detect their presence and save your presentation as a .pptm file. You can force PowerPoint to save a presentation that includes macros as a .pptx file, but PowerPoint won’t let you play the macros that you’ve included in your slide slow. So it’s best to let it save your file with the .pptm extension.

If you need to share your presentation with a colleague who is using an older version of PowerPoint, then save your slides as a .ppt file. PowerPoint 97 through 2003 cannot open and process .pptx or .pptm files.

If you’re using PowerPoint 2007 or newer, you should always save your work in .pptx format (or in .pptm format if you’ve used macros in your presentation). The options described below are additional ways to save your work. Be sure to save them first as ordinary .pptx or .pptm files before you save them in any of these other formats.

PowerPoint Shows

If you want to give your PowerPoint presentation to a friend or colleague, and you don’t want them to change anything, then save your presentation as a PowerPoint Show file. Your colleagues can display your slides, but they will be unable to change any part of your presentation.

There are three types of PowerPoint Shows: Save an ordinary presentation as a .ppsx file. If you’re using macros in your presentation, save it as a .ppsm file. If you’re sending your slide show to somebody who is using PowerPoint 97 through 2003, then create a .pps PowerPoint Show file.

Be sure to save your presentation as a plain vanilla (.pptx) file or as a macro-enabled (.pptm) file. If you’ve only saved the Show file, you won’t be able to make changes to your presentation.

PowerPoint Picture Presentations

Picture Presentations add an additional layer of protection to your work. To the casual observer, a PowerPoint Picture Presentation looks like an ordinary PowerPoint slideshow. But when you save your work as a Picture Presentation, each slide is converted to a simple image.

Slides contain text objects, image objects, animations, transitions, and many other special effects. By contrast, Picture Presentations contain only snapshots of your slides.

If somebody wants to copy your work, they can see each of the images and retype the text. They can even grab (and re-crop) the images. But they cannot capture any of the magic that is PowerPoint.

If you create a Picture Presentation, be sure to give it a unique name. If you only save the Picture Presentation .pptx file, you won’t be able to modify your presentation in the future.

Windows Media Videos

You can convert your PowerPoint presentation to an ordinary Windows Media Video (.wmv) file, and play it using the built-in Windows Media Player or any other video player. Your .wmv file can be enjoyed by any Windows or Mac user, even if they don’t have PowerPoint installed on their computer.

As always, don’t make your .wmv file the only version of your slideshow or you’ll be very disappointed when you want to make changes to the presentation.

Outline/RTF

PowerPoint lets you turn your slideshow into plain text. This is handy if you want to move some of the presentation’s text to your website or blog.

When you create a rich text format (.rtf) file, you save only the text. You lose all of the images, animations, slide-to-slide transitions, and other non-text objects.

It’s easy to save your presentation as a portable document format (.pdf) file. These .pdf files can be opened on any Windows, Mac, Unix/Linux, iOS, or Android device. The resulting file, however, is a static document. Don’t expect to see slides fade in and out. All of your animated objects will become static.

You can save your slides as an XML Paper Specification (.xps) file. That’s a fancy way to say that if you double-click your .xps file in Windows Explorer, the operating system will open your file using its built-in XPS Viewer.

The XPS format is ideal for sending your slideshow to users who have neither PowerPoint nor Adobe Acrobat Reader installed on their computers. As with the .pdf format above, .xps files have text and images, but no animation.

If you’re happy with this year’s Financial Results slideshow, and you want to create next year’s presentation using the same colors and fonts, then save your current presentation as a template, and use it over and over.

As you may have guessed, save your work as a .potx file for use in PowerPoint 2007 and newer, as a .potm file for a 2007 or newer macro-enabled presentation, and as a .pot file for use on PowerPoint 97 through 2003.

Office Themes and Backups

Because Microsoft PowerPoint is part of Microsoft Office, you can use two Office file types to make your PowerPoint work easier and safer.

You can save your presentation theme as an Office .thmx file. Future PowerPoint presentations, as well as Word documents and Excel spreadsheets, can use this Office theme to set their fonts and colors. This results in a consistent look and feel to all of the Office documents that you present to prospects and customers.

Autosave is built into most Office applications, including PowerPoint. If you experienced a power outage and hadn’t saved your PowerPoint presentation before you lost power, it’s possible that there’s a recent version of your slideshow in the Office Autosave library. If you click File , click Open , and click Recover Unsaved Presentation , you may be pleased by the information that PowerPoint saved for you.

The Bottom Line

There’s no need to memorize all of the PowerPoint file extensions and options that are available. But be sure that you’re including all of these files when you do your regular on-site and off-site backups. And bookmark this blog page so that you can return to it when you need to save or open a PowerPoint presentation in one of the less popular file formats.

Getting Started OpenXml and PowerPoint [closed]

I would like to develop a class library that could process PowerPoint templates, and populate formatted data. Mainly involving tables, labels, slide cloning. I would like to use Open Xml for this with .Net 4.

I would like some recommendations and references for this. Also would like to know which approach is good, whether to go with OpenXml SDK 2.0 or System.Packaging because I read in some places that using Open Xml SDK consumes bit more memory.

Thanks, Aneef

• openxml-sdk

• I believe the Open XML SDK 2.5 is required for .NET 4? –  Paul C Commented Apr 8, 2013 at 9:22

4 Answers 4

The Open XML SDK 2.0 is built on top of System.Packaging so it will be easier to write and maintain the code. I found I was able to write two lines of Open XML SDK code whereas when I had wrote it using System.Packaging it was over 200 lines. As far as using more memory, I have not ran into any issues and have found maintainability and readability to out weigh the minimal increase in memory usage.

There aren't many resources out there for using the Open XML SDK with Power Point, but here are two to get you started:

Brian Jones & Zeyad Rajabi blog

I would first recommend you understand the Presentation Markup Language (PresentationML) before you start using any of the APIs.

There is a free online book that describes PresentationML, WordML, and SpreadsheetML called Open XML Explained . Chapter 3 describes PresentationML and gives you the knowledge required to better use the OpenXML API to do all of the tasks you need to do.

A good start for me was using the Document Reflector ( Reflect Code tool in the Open XML Productivity Tool of SDK 2.5). Load a .pptx and get the C# code to generate that .pptx - so you learn the structure of PresentationML and get an idea where to put the parameters and options you want - it's not easy, but a good start

A great way to learn OpenXML FAST is to observe how powerpoint uses it! My technique is unconventional, yet blazing fast to get into weeds and start delivering value ASAP!

• Save a new powerpoint - start with 0 slides
• Create a new directory, same name as your ppt, adjacent to it
• initialize this as a git repo
• Build a new script called unpack-pptx.sh
• run this script with your ppt file
• Reformat the xml to be readable, commit the changes in your directory
• Make changes to the presentation in powerpoint, save and rerun the script, reformat again
• Observe how powerpoint modifies the XML schema! Pay particularly attention to the presentation.xml, the slide files, and the *.rels files

This is a classic reverse engineering technique that lends great to fast and scrappy learning. Pair this up with ChatGPT for questions and you're off to the races!

p.s. Once you start using OpenXML SDK in C#, use intellisense to read the docs! Pay attention to namespaces and hints about what the class represents in it's XML form.

Learn about file formats

A file format specifies how data is stored for a particular application. For example, a .docx file is an Open XML formatted Microsoft Word document. Not all applications can read all file format; and in some cases an application may only be able to read parts of the file. For example, a application may be able to read the text, but not the formatting, of a file that uses a format other than its own.

OpenDocument Format (ODF) was originally developed to support the features and behavior of OpenOffice-based productivity suites and Open XML was originally developed to support the features and behavior of Microsoft Office.

Microsoft Office now provides support for ODF and gives people using Microsoft Office the chance to save their Office files in ODF. However, because Microsoft Office and OpenOffice features aren’t exactly the same or aren’t implemented the same way, people who use unsupported features and save Office files in ODF might experience changes in how they can work with the file and sometimes see a loss of content.

The Open XML format (.docx/.xlsx/.pptx) is the default format in all supported versions of Microsoft Office and, unless you have a specific reason to use a different format, it's the format we recommend using for your Office files.

To learn more about the Open Document Format (ODF) generally see  OASIS Open Document Format for Office Applications .

PowerPoint to XML

XML is a format used to store data that can contain not only text but also binary information or media like images, audio, video. It uses a structured format and nowadays it is widely adopted in many different sectors to exchange data between computers and as a file format that is easily versionable.

Recent versions of PowerPoint supports XML format in its new PPTX output format for presentations (actually it is a zip archive that if you rename from pptx to zip you can open it in WinRAR or WinZip and then find a lot of .xml files inside with presentation media and resources). But if you still need to save your presentation to .xml then you can do that in the Save As dialog.

Go to File and then Save As and now you can open the Save as type to choose PowerPoint XML Presentation (*.xml). Once accepted, your presentation will be saved to XML.

Viewing the XML File

You can open XML files for editing using a plain text editor or any other XML tool. At a glance you will see a series of complicated tags and code that contain the data regarding your PowerPoint presentation but after checking carefully you will notice the data is well structured and it can be easily handled by an application or converter

What Is a PPTM File?

Open and edit a macro-enabled PowerPoint presentation for free with WPS Office, Google Slides, or PowerPoint Online

• Emporia State University
• Google Drive
• Backup & Utilities
• Cryptocurrency

What to Know

• A PPTM file is a macro-enabled presentation file created by PowerPoint.
• View and edit one for free with WPS Office , PowerPoint Online, or Google Slides.
• Convert to PDF with FileZigZag , or use PowerPoint to save to PPTX, MP4, etc.

This article explains what PPTM files are, all the different ways you can view or edit one, and how to convert the slideshow into a different format like PDF or PPTX, or a video format like MP4 or WMV.

A file with the PPTM file extension is a Microsoft PowerPoint Open XML macro-enabled presentation file. They're comprised of pages/slides that hold text, media files like images and videos, graphs, and other things pertinent to a presentation.

Like PowerPoint's PPTX format, PPTM files use ZIP and XML to compress and organize the data into a single file. The difference between the two is that PPTM files can execute macros, while PPTX files, although they might contain them, can not.

PPSM is a macro-enabled file similar to PPTM, but is read-only by default and immediately starts the slideshow when opened. PPTM files let you edit the contents right away after double-clicking the file.

How to Open a PPTM File

If you just need a super quick way to view the contents of the file without any editing or conversion tools, and without needing to make a user account, use GroupDocs .

However, for full editing power, use Microsoft PowerPoint 2007 or newer. If you have an older version, you can still open the file if you have the free Microsoft Compatibility Pack installed.

PPTX files can run scripts that have the potential to be malicious, so it's important to take great care when opening executable file formats like these that you may have received via email or downloaded from websites you're not familiar with. See our List of Executable File Extensions for a listing of file extensions to avoid and why.

PowerPoint Online is one of Microsoft's free PowerPoint viewers that fully supports opening PPTM files as well as saving back to the same format. Files you open there are stored in OneDrive.

Similar to PowerPoint's online editor is Google's, called Slides . It's totally free to view and edit PPTM files. Files you upload there are stored on Google Drive.

The free WPS Office works with this format as well, letting you open, edit, and save to various PowerPoint formats. That same company has an online version at WPS Cloud where you can view and edit the file.

Another way to open (but not edit) PPTM files without PowerPoint is to use Microsoft's free PowerPoint Viewer program.

The following free software can open and edit PPTM files as well, but they make you save the file to a different format (not back to .PPTM): OpenOffice Impress , LibreOffice Impress , and SoftMaker FreeOffice Presentations .

If you just want the images, audio, and video content from the file, but you don't have a PPTM reader or editor installed, you can open the file as an archive with 7-Zip . Look in the ppt > media folder for those types of files.

How to Convert a PPTM File

The easiest way to convert the file is to use one of the PPTM viewers/editors from above. Once the file is open in the program, you can save it to another format like PPTX, PPT, JPG, PNG, PDF, and many others.

To convert PPTM to an MP4 or WMV video, use PowerPoint's File > Export > Create a Video menu.

WPS Office's desktop application is one way you make image files out of the slides.

You can also use the free, online file converter FileZigZag to convert the slideshow to a variety of formats, including PDF, ODP, POT, SXI, HTML, and EPS.

Still Can't Open It?

This file extension closely resembles the PTM extension used for MapPoint map files and PolyTracker module files. If your file doesn't work with the presentation software mentioned above, check the file extension again, because it might only work with a program like Winamp (if it's a PTM file).

Another example of file extensions that can easily be mixed up for a PPTM file is PTP and PTX , which are both related to Avid Pro Tools.

How to Recover Unsaved PowerPoint from Windows PC

Can I recover unsaved PowerPoint from Windows computer? In this post, you can learn some tricks to safely recover unsaved PPT or PPTX files from Windows.

By Lucas / Updated on August 13, 2024

Way 1. Restore unsaved PPT/PPTX from Recent Files Folder

Way 2. recover ppt, pptx files using windows file recovery, way 3. recover ppt, pptx files from temp folder, way 4. recovering ppt, pptx files with auto-recovery, way 5. recover unsaved powerpoint (ppt, pptx) files with data recovery tool, overview of powerpoint files.

The primary file extension for PowerPoint presentations is PPT, which is an abbreviation for the Microsoft PowerPoint Presentation binary format. The software is frequently employed to create presentations for educational and commercial purposes. Texts, images, videos, and slides are all preserved within the PowerPoint file.

Nevertheless, the default file format for Microsoft PowerPoint has been PPTX since 2007, and subsequent versions have since supplanted it. It compresses files by integrating both XML and ZIP formats. Slide presentations in the PPTX file format can only be viewed by users with older versions; they cannot be edited.

PowerPoint presentations are both efficient and beneficial. They provide visual support for discussions, lectures, and other events. The loss of critical information can result from the deletion or loss of these files. Numerous data recovery methods can be employed to address these circumstances.

5 ways to recover unsaved PowerPoint

In this part, we’ll help you retrieve unsaved PowerPoint files on your PC.

Step 1. Open the windows menu and type in File History. This will open up the control panel.

Step 2. Make sure you have turned on the File History option. If not, select an internal or external drive to which you want to back up your information, and turn it on.

Step 3. Now, click on the Restore personal files option.

Step 4. Go through available backups and locate the PPT or PPTX file you want to recover.

Step 5. Once you’ve found your file, click on the green recover button at the bottom. Your file will be restored to its original location.

You can get Windows File Recovery from the Microsoft Store for free. It is Microsoft's command-line recovery tool. Users must enter the appropriate command prompt to get back lost files because it doesn't have a graphical user interface. This tool helps you get back lost info and works with many file systems and types.

Step 1. Download Windows File Recovery from the Microsoft Store and Install it on your PC.

Step 2. Launch Windows File Recovery and click the Run as administrator option. Once the Command Prompt window opens, enter the command in the following format:

winfr source-drive: destination-drive: [/mode] [/switches]

You need to specify a mode in the format mentioned above, according to what’s suitable for your file system. You can use two basic modes to recover files – Regular and Extensive.

You can also mention any specific file extensions according to the files you wish to retrieve. For instance, enter a similar command to retrieve PPT, PPTX files:

winfr C: E: /extensive /n *.ppt /n *.pptx

Note that the source and destination drives must be different. After you’ve entered, Microsoft automatically creates a recovery folder on the destination drive.

Step 3. Now, enter Y to start the recovery operation. This may take some time, depending on the size of your source drive and your recovered files will be saved on the destination drive.

Another way to get back PPT and PPTX files that you haven't saved is to use the temporary files folder. This temporary area in Windows is where files from different programs can be saved.

Step 1. Press Win + R and type in %temp% in the Run prompt.

Step 2. Once you run the command, the folder window will open in File Explorer. To narrow down your search options, you can filter through the results by using the following extensions – *.pptx, *.ppt, ppt*.tmp .

Step 3. If the presentation is located within the temporary files folder, it should show up in the results and it’ll be possible to recover it.

PowerPoint has tools that can help you get back files that you have lost or not saved yet. Since 2010, all versions have had both the Auto Recovery and Recover Unsaved Presentations options. The first one automatically saves the file you're working on at set times. Both of these tools help the user make sure they have a place where they can get back lost files.

When you work on a PPT or PPTX file and don't save it yet, PowerPoint makes a temporary folder to save it. Your file might be in the Auto-Recover File Location, which you can find. But make sure that the Auto-Recover information option is turned on before you can use this tool.

Step 1. To check AutoRecover on Windows: Open File > Options > Save > Save Presentations > Save Auto-Recover info.

Tip: If PowerPoint or your system crashes while you’re working or before you have the chance to check a saved version, you can go to: Open File > Info > Manage Versions > Recover Unsaved Presentations.

If you lose your unsaved PowerPoint files because of a system crash, PC problems, or a disk data wipe, you should use a data recovery tool as your first option. This is because you are likely to lose more files than just your PPT files in these situations. Yes, data recovery tools can get back your lost files as soon as possible. But if you do more work after the fact, you might overwrite some data, which will make recovery tools less useful.

AOMEI FastRecovery can get back PPT and PPTX files and other files in an easy-to-use interface without having to go through a lot of steps. It doesn't require you to find and restore the target files at the same time as the built-in tool does; it can quickly scan and find the files you want to restore.

It works with all versions of Windows and makes it easy to get back lost files from SSDs , HDDs, SD cards, USBs, and more.

Step 1. Install and launch AOMEI FastRecovery. Choose the exact partition or disk where your data lost and click Scan.

Step 2. Then, the recovery tool start to scan and search. lt will execute the “Quickly Scan" first for finding your deleted data fast, and then execute the “Deep Scan" for searching other lost data.

Step 3. Once the scan is completed, all deleted files, recycle bins and other missing files will be displayed. Please select the file you would like to recover and then click "Recover".

Step 4. Then, select a folder path to save your recovered files.

Step 5. Wait patiently for this process of recovering ends.

To recover unsaved PowerPoint, we offer you 5 solutions that can help you save your lost data. We suggest you don't do other operations when you find your PPT document disappears but it's unsaved. Normally, Microsoft Office has automatic save when you're using it. So, you can try the PPT tool first. If it's not working, AOMEI FastRecovery will help you. This powerful tool can quickly retrieve lost files from hard disks and portable devices, you can trust this tool to avoid data loss in most spots.

Insert a new slide into a presentation

• 3 contributors

This topic shows how to use the classes in the Open XML SDK to insert a new slide into a presentation programmatically.

Getting a PresentationDocument Object

In the Open XML SDK, the PresentationDocument class represents a presentation document package. To work with a presentation document, first create an instance of the PresentationDocument class, and then work with that instance. To create the class instance from the document call the Open(String, Boolean) method that uses a file path, and a Boolean value as the second parameter to specify whether a document is editable. To open a document for read/write, specify the value true for this parameter as shown in the following using statement. In this code segment, the presentationFile parameter is a string that represents the full path for the file from which you want to open the document.

• Visual Basic

The using statement provides a recommended alternative to the typical .Open, .Save, .Close sequence. It ensures that the Dispose method (internal method used by the Open XML SDK to clean up resources) is automatically called when the closing brace is reached. The block that follows the using statement establishes a scope for the object that is created or named in the using statement, in this case presentationDocument .

Basic Presentation Document Structure

The basic document structure of a PresentationML document consists of a number of parts, among which is the main part that contains the presentation definition. The following text from the ISO/IEC 29500 specification introduces the overall form of a PresentationML package.

The main part of a PresentationML package starts with a presentation root element. That element contains a presentation, which, in turn, refers to a slide list, a slide master list, a notes master list, and a handout master list. The slide list refers to all of the slides in the presentation; the slide master list refers to the entire slide masters used in the presentation; the notes master contains information about the formatting of notes pages; and the handout master describes how a handout looks. A handout is a printed set of slides that can be provided to an audience . As well as text and graphics, each slide can contain comments and notes , can have a layout , and can be part of one or more custom presentations . A comment is an annotation intended for the person maintaining the presentation slide deck. A note is a reminder or piece of text intended for the presenter or the audience. Other features that a PresentationML document can include the following: animation , audio , video , and transitions between slides. A PresentationML document is not stored as one large body in a single part. Instead, the elements that implement certain groupings of functionality are stored in separate parts. For example, all comments in a document are stored in one comment part while each slide has its own part. © ISO/IEC29500: 2008.

The following XML code example represents a presentation that contains two slides denoted by the IDs 267 and 256.

Using the Open XML SDK, you can create document structure and content using strongly-typed classes that correspond to PresentationML elements. You can find these classes in the DocumentFormat.OpenXml.Presentation namespace.
