Are previously downloaded Steam games transferable from Windows to Linux? - Reddthat

I’ve backed up many of the Steam games I had installed in Windows. Am I able to use these on Linux or do I need to re-download them?

Yup, you’ll be fine. If a game has a Linux version though, you’ll still need to download some portion of it. By the way, just don’t use NTFS to play on Linux.
Thanks. I don’t mind dling some additional stuff I just would prefer to avoid the bulk of it.
No problem! By the way, if Linux version of a game is broken (you’ll encounter those), or if you want to use Proton regardless, set a Proton version for that game before installing and you can restore your backup without downloading anything.
