Where is the Steam folder on Linux?

Every Steam application has a unique AppID, which you can find out by looking at its Steam Store page path. Steam installs games into a directory under LIBRARY/steamapps/common/ . LIBRARY normally is ~/. steam/root but you can also have multiple library folders (Steam > Settings > Downloads > Steam Library Folders).

How do I find where Steam is installed?

Steam Library

Right-click a game and select Properties from the context menu. In the Properties window, go to the Local Files tab and click Browse Local Files. File Explorer will open to where the game’s local files are stored. Read the path in the location bar and you’ll be able to find where your Steam folder is.
