Save file locations

Windows (Steam)
%USERPROFILE%\Documents\My Games\Binding of Isaac Repentance

Full path: C:\Users\<YourName>\Documents\My Games\Binding of Isaac Repentance\ . Save slots are rep_persistentgamedata1.dat / 2 / 3. Repentance+ uses the 'Binding of Isaac Repentance+' folder.

PlayStation (PS3/PS4/PS5)
Settings › Saved Data and Game/App Settings › Saved Data

Console saves are sealed and can't be copied as raw files. Back them up to PS Plus cloud or a USB drive from this menu.

Xbox (360 / One / Series X|S)
My games & apps › <Game> › Manage game › Saved data

Xbox saves sync automatically to the cloud with your Microsoft account; there is no user-accessible save file on disk.

Nintendo Switch
System Settings › Data Management › Save Data Cloud

Switch save data stays inside the system storage and can only be backed up via Save Data Cloud (Switch Online), not copied as loose files.

Cloud saves

The Steam version can use Steam Cloud, and a SteamCloud key in options.ini (same Documents folder) decides whether the live save is the local one or the cloud copy at Steam\userdata\<SteamID>\250900\remote. If unlocks look wrong after switching PCs, keep the copy with the most unlocks and let it sync up.

How to open the save folder

  1. Press Win + R to open the Run box.
  2. Type %userprofile%\Documents\My Games and press Enter.
  3. Open Binding of Isaac Repentance (or Repentance+).
  4. Copy the rep_persistentgamedata*.dat files somewhere safe before reinstalling or modding.

Save problems & fixes

Binding of Isaac unlocks reset or save won't load

A Steam Cloud conflict often overwrites unlocks — restore a backup rep_persistentgamedata*.dat into Documents\My Games\Binding of Isaac Repentance, and check the SteamCloud value in options.ini so the game reads the right copy.

Isaac save missing after switching PCs

Copy rep_persistentgamedata*.dat from the old PC's Documents\My Games\Binding of Isaac Repentance, or sign into the same Steam account and let Cloud sync before launching so it doesn't push an empty save.
