Quasimorph Save Location: Where Your Files Are Stored
The exact Quasimorph save file location on Windows and Steam Deck, plus how to safely back up and restore your saves without breaking a run.
On Windows, Quasimorph saves are stored at C:\Users\[YOUR_USERNAME]\AppData\LocalLow\Magnum Scriptum\Quasimorph, inside a Saves folder specifically. On Linux or Steam Deck, the equivalent path is ~/.steam/steam/steamapps/compatdata/2059170/pfx/drive_c/users/steamuser/AppData/LocalLow/Magnum Scriptum/Quasimorph/ — 2059170 is Quasimorph's Steam App ID, which is why it shows up in the path.
How to find the folder quickly on Windows
The AppData folder is hidden by default. The fastest way in is pressing Windows Key + R, typing %appdata%, and navigating back up one level into LocalLow from there, then into Magnum Scriptum\Quasimorph\Saves.
How to back up your saves
Copy the entire Saves folder rather than individual files — character rosters and progression data need to stay in sync with each other, and copying only part of the folder risks breaking that sync. Put the copy in a dated backup directory on a separate drive or your desktop so you can tell backups apart later.
How to restore a backup
- Close the game completely: Don't attempt to restore files while Quasimorph is still running.
- Disable Steam Cloud temporarily: Go to the game's Properties in Steam and turn off Cloud sync, or it may overwrite your restored files on next launch.
- Delete the current Saves folder entirely: Don't just overwrite files inside it — remove the whole folder first.
- Paste your backup Saves folder into the original location: This replaces the deleted folder with your backed-up version.
- Relaunch the game and re-enable Steam Cloud if you want it: Turn Cloud sync back on once you've confirmed the restored save loaded correctly.
Warnings before you restore anything
Dying means losing everything anyway
Quasimorph's core rule already applies before you touch any files: "if you die, you lose everything" carried by that clone. A save restore doesn't get around that — it just returns you to an earlier point where that loss hadn't happened yet.
Restoring a save mid-raid, rather than at a safe point like being docked at your ship, can potentially cause map generation issues, since the game may not expect a mission state to be loaded that way. Backups taken before deploying on a mission, or right after returning to the ship, are meaningfully safer to restore from than ones taken mid-mission.
