You can use 7-Zip on any computer, including a computer in a commercial organization. You don't need to register or pay for 7-Zip. How To Install 7Z / Zip Files

: Install the p7zip-full package via your terminal to manage .7z files.

: Tools like The Unarchiver are common for handling this format.

Are you trying to these files into a specific program, or just looking to extract them?

Because the file itself is a .7z archive, you need a compatible decompression tool to "look into" it:

: Use the official 7-Zip program or WinRAR by right-clicking the file and selecting "Extract Here" .

: A minimal standalone version that exclusively handles .7z archives.
