Konverter CAB-filer til POTM i Java

What is CAB file format?

CAB (or Cabinet) is a common file format used to compress and archive files, commonly used in Microsoft Windows. CAB files are created using the MakeCab command-line tool that is included in Windows and also supported by other compressed file programs. CAB files contain one or more compressed and/or encrypted files in the cabinet format. This format uses embedded file pointers that can be securely transported without being extracted, making them a popular choice for software publishers and developers who need to deliver files in a self-contained package. CAB files can also be distributed via a server, or downloaded from the Internet and then installed. CAB files are ideal for storing and transferring large files, as they can easily be compressed to reduce the file size. The files also remain secure due to their internal file pointers, as they cannot be opened or accessed without the proper software. In addition, CAB files are great for a software publisher who needs to deliver large files quickly and efficiently.

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.
