What’s the best way to unzip a .7z file on SteamOS?

I noticed you’re on SteamOS, so while Ark is installed by default, you might find it easier just to switch to a different distro if you encounter too many issues. Alternatives like Bazzite or Nobara could simplify things for you.

If you're looking to unzip .7z files, P7ZIP is a solid choice. It’s designed to work with these types of files, especially since they were originally made for Windows. You can easily install it using your package manager.

If you're more comfortable with a graphical interface, I recommend trying PeaZip. You can find it in the Discover software center, and it's pretty user-friendly for unzipping various file formats.
