If you're running a Windows game, it will be in the Wine prefix that you're using for the game.

Newbie here - trying to help but probably just wasting your time (you know my type). I've mostly found similar files in ~/Documents, so these are straws to grasp at.

~/[distro-dependent]/steamapps/compatdata/[your-app-ID]/pfx/users/steamuser/Documents
~/[distro-dependent]/steamapps/compatdata/[your-app-ID]/pfx/drive_c/users/steamuser/Documents

I've not seen an app store files there but it seems like a remote possibility. Maybe take a peek in AppData/Local as well as Documents while you're there. (I have seen config files there, but it sounds contrary to your instructions.)

My other thought is even more of a long shot. Choose Manage/View Local Files... for your program from Steam and check whether this config file got mixed in with main/non-config program files. Shouldn't happen but ya never know.

Edit after reading @WarnerCK. Under pfx/users pfx/drive_c/users, a few of my apps have my actual username as well as steamuser. On my lubuntu 22.04 system, the Documents subfolder in that directory is a link to ~/Documents. But that might be distro-dependent. Another thing/place to check.

When I'm looking for a config file or save games of any game, in using the "locate" program. Might need to be installed first and having it's database generated. Then I'm using like "locate -i gamename". That said, the desktop environments probably can do similar things for you.

(replying to your comment just to keep this a 'lil organized)

File managers (Krusader is quite powerful) have good GUI search features for this.

For commandline, without having to update a database every time there's a new file:

find ~ -iname '*some*file*cfg'

You can usually narrow it down a bit to only search your steam folder:

find ~/.local/share/Steam -iname '*some*file*cfg'

Remember to put single quotes around the name if you're adding * wildcards (otherwise the shell will mess with those * and turn them into something else).

With the usual tradeoff, yes.

Is this for Proton games? Because I found config files like everywhere under home...

Afaik. all game related configs are supposed to be contained within the wine/proton folder steam designates for the game, or within the steamapps folder for games in general.

WINE/Proton games yes, but native games won't do that (and rightfully so, IMHO).

right click game icon -> properties -> updates -> take note of steam appid # -> navigate to steamapps/compatdata/{steamapp id #}/pfx/drive_c/users/steamuser/Documents

If you have OneDrive enabled, it's likely in C:\Users\$user\OneDrive\Documents

mostly in these 4 folders


/Documents is only for files you put there yourself, its not like a grab box of "My Documents" where windows throws all the junk
