What is LZ file format?

LZ File Format is an open-source archive file format developed by Igor Pavlov and used mostly to compress and decompress other files. It is widely used in the Windows and Linux operating systems, and is supported by many programs, such as WinZip, 7-Zip, WinRAR, and WinAce. The format’s name came from the developer’s initials — Lempel-Ziv. Files stored in LZ format contain compressed data in a format similar to a zip or tar file. They are often smaller than the original files, and when opened, can be decompressed to restore the original data. The primary benefit of using LZ format is that it allows the user to reduce the amount of data they must store without losing any of the quality of the original files. The LZ file format is also sometimes referred to as a “Lempel-Ziv archive” and is considered a “lossless” compression format, as none of the data is lost when a file is compressed using the LZ format. This is because unlike lossy compression formats, LZ format retains all of the original data when files are compressed and decompressed. The LZ format is also highly flexible and able to store a variety of different types of data, including text, audio, video, and image files. It is also compatible with encryption tools, making it a great choice for users who need to protect their data. Overall, there are many benefits to storing data in the LZ file format, such as reduced storage space and the ability to encrypt data for security. If you are looking for an easy-to-use, flexible, and reliable archive file format, LZ is an excellent choice.

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.
