What is SHAR file format?

SHAR files are compressed archives created by Unix Shell Archive Program. They can store multiple files in one archive and compress them with a shell script. This script allows the files to be recreated by running a command. SHAR files are different from other archivers because they need the UNIX Bourne shell to work properly. They are also called self extracting compressed files. SHAR files are text files that can create other compression utilities. They are command-line driven programs that need a specific SHAR command to execute. SHAR files can also copy the functions of a UNIX script, making them important shell scripts. To unpack SHAR files, type “sh filename.shar”.

To open a .shar file, double-click it and Windows will launch the right application. If not, you may have to download or buy the correct application. Or you may have to set up the file associations correctly. This means telling Windows which application to use for .shar files. Once you do that, opening a .shar file will open the correct application.

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.
