Where Are Gloomhaven Save Files Located?
Gloomhaven saves campaigns in AppData\LocalLow\FlamingFowlStudios\Gloomhaven\GloomSaves on Windows (plus a Beta folder), with per turn checkpoints inside each campaign.
Last updated
Gloomhaven stores campaigns outside the Steam folder in the Unity LocalLow tree. Each campaign gets its own folder under GloomSaves with checkpoint saves inside, written every turn and before scenarios. A separate Beta folder holds beta branch campaigns apart.
The folder layout makes rescue practical. Checkpoints accumulate per campaign, so rolling back means promoting an older checkpoint file rather than replaying hours. Mods and settings sit beside the saves in the same parent, worth grabbing in the same backup pass.
Where Gloomhaven stores this, by platform
%USERPROFILE%\AppData\LocalLow\FlamingFowlStudios\Gloomhaven\GloomSaves
One subfolder per campaign with Checkpoints inside. Copy whole GloomSaves folder with game closed for backups. Beta branch campaigns use GloomSavesBeta instead.
~/Library/Application Support/unity.FlamingFowlStudios.Gloomhaven
Same GloomSaves layout under Unity macOS naming. Reach with Finder Go to Folder. Mods folder sits beside saves for full backups.
~/.local/share/Steam/steamapps/compatdata/780290/pfx/
Proton prefix for app ID 780290 with the Windows tree mirrored inside. Steam root varies by install type. Copy saves out before reinstalling Proton versions.
Frequently asked questions
How do I restore a corrupted Gloomhaven save?
Open the campaign folder in GloomSaves and look for Checkpoints and ScenarioCheckpoints subfolders. Copy one checkpoint file up a level, stripping the number, and restart the game between tries. Save dates matter more than file numbers.
How do I back up my Gloomhaven campaign?
Copy the whole GloomSaves folder with the game closed. Cloud sync covers Steam copies, but local backups save you when sync conflicts eat progress. Each campaign keeps its own subfolder, so partial restores work.
