  2. File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/563560/ in addition to or instead of this directory. The app ID (563560) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
