Steam Cloud is not listed for the launch build; back up the Saves folder before manually transferring it between Windows, Steam Deck, Bazzite, or another Proton device.

How to Fish does not list Steam Cloud in its official launch feature set, and current players report moving save files manually. Before any transfer, close the game on both devices and copy the entire Saves folder to a separate backup location. Do not overwrite the destination until the backup exists.
Reported Windows save location
C:\Users\<your-user>\AppData\LocalLow\Dazed Games\How to Fish\Saves\
AppData is normally hidden. Open the user's profile folder with hidden items visible, then follow LocalLow, Dazed Games, How to Fish, and Saves. The path is community-reported rather than developer-documented, so confirm that the files change after a new save before replacing anything.
Reported Steam Deck, Bazzite, or Proton location
<SteamLibrary>/steamapps/compatdata/4001890/pfx/drive_c/users/steamuser/AppData/LocalLow/Dazed Games/How to Fish/Saves/
The confirmed report came from Bazzite. Steam Deck also uses Proton for this Windows game, but its Steam library prefix can differ depending on internal storage, microSD use and library configuration. Search inside the compatdata/4001890 prefix rather than copying the reporter's mount point literally.
Safe manual-transfer checklist
- Exit How to Fish completely on both devices.
- Copy the source
Savesfolder to a dated backup. - Copy the destination
Savesfolder to a different dated backup. - Transfer the source contents into the destination folder.
- Start the game and verify the expected island, gear and objective.
- If progress is wrong, close the game and restore the destination backup.
Because Steam Cloud is not currently listed, do not assume Steam will reconcile two different saves. Recheck the official feature list after patches; if the developer adds Cloud later, the manual process may no longer be necessary.
