Convert MPT to POTM in C# .NET

What is MPT file format?

MPT (Multi-Purpose Tray) is a file format that was created by Microsoft in order to provide an easy way to create and store documents. The MPT format is based on a template system, enabling users to open and save documents that include multiple pages and can be edited in the same way as a traditional document. MPT files are structured similarly to other document file formats, such as Microsoft Office documents and PDFs. The main difference is that MPT allows for users to easily add more pages to the document, as well as create additional sections, to which they can add additional content. This makes it a great format for printing documents, as pages and sections can be added and deleted as needed. MPT files are saved as .MPT or .MPS files, depending on the version of Microsoft Office being used. The format is widely supported and compatible with a variety of other programs, including Microsoft Word and OpenOffice. Files can be converted to other formats for use in other applications.

MPT files are great for creating documents that need to be shared with others, such as workgroup assignments, user documents, and business reports. They also provide a great way to store multiple pages of content in a single file, while still allowing individual pages to be moved, edited, and updated.

What is POTM file format?

A POTM file refers to a macro-enabled presentation template created using Microsoft PowerPoint, a software program used for creating slide show presentations. It includes default images, slide templates, macros, and formatting. POTM files are commonly used by PowerPoint users to create multiple .PPTM files with consistent designs and macro settings.

POTM files offer additional functionality compared to typical presentation files, as they support macros. Macros are script-like functions that automate repetitive tasks within PowerPoint. Users can record macros that can be replayed to perform specific actions and assign them to buttons or keystrokes for convenient execution. To record a macro, users can select View → Macros in PowerPoint.

For general presentation creation, users can save their files as .PPTX or .POTX files. However, if they want to create a template that incorporates macros, they can save their presentation as a POTM file.

It’s worth noting that POTM files were introduced by Microsoft when they released Microsoft Office 2007.

To open a POTM file, Microsoft PowerPoint (2007 or later) is the recommended application for full support of presentation formatting and embedded macros on both Windows and macOS. Alternative applications like Apache OpenOffice Impress, Kingsoft Presentation, and Apple Keynote can also open POTM files, but some formatting and macros may not be fully preserved. For Mac users looking to view a POTM file without editing, Apple Preview (bundled with macOS) or Google Drive, a free cloud storage service, can be used.

Online platforms like Google Slides allow users to upload POTM files for viewing, editing, and conversion. However, it’s important to note that Google Slides does not support macros.

To convert a POTM file, various presentation applications including Microsoft PowerPoint, Apple Keynote, and OpenOffice Impress offer conversion capabilities. In Microsoft PowerPoint for Windows and Mac, users can select File → Save As and choose from formats such as .PPTX, .PPT, .PDF, .ODP, .XPS, .MP4, .WMV, .JPEG, and .PNG to convert the POTM file to their desired format.
