Linux Gaming

Might be a stupid question, but bear with me, I just started the transition to Linux!

I've been playing a game on Steam for some time now, and modding it was a huge hassle (not modding it per se, but rather make every mod work together, incompatibilities, merging, etc., you know the drill), so I'd rather NOT do that again from scratch (especially because the mod organizer tool I used is only for Windows, unless I can run that through Proton?); on the other hand, if I wait until I beat the game, it's going to delay the move to Linux a lot, months.

I think most of the files needed to run the modded game lie in the game folder, some user settings needed for the mods to work correctly are in the game's Documents folder; would I be able to just crudely copy-paste these two folders from Win to Linux? If yes, I guess I have to use an external drive to do so, since I can't access each other OS's partitions while I'm on one or the other, correct?

If you need more info feel free to ask; as I said I just started moving to Linix so I probably forgot important info! Thanks in advance

edit: don't know if websearches return Lemmy threads, but just in case: I installed the game via Steam on Linux and launched it once through Proton. After that, I just copy-pasted the folders that cointan mods from the Windows drive to the Linux drive and then the game's document folder as well (although this one doesn't go into the Linux's Documents folder, rather in a Documents folder inside the Steam directory of the game). Game boots with no script compiling errors (meaning everything went well with the simple copy-paste). Haven't played yet apart from a quick load to confirm that mods were working, but usually if the game starts there won't be problems down the line! Guess I can start booting Linux instead of Win for the most part! Thanks everyone for the help!
