Where Are Kerbal Space Program Saves Located?
Kerbal Space Program saves folder inside the game install directory, one subfolder per career or sandbox.
Last updated
KSP keeps saves inside its own install folder under saves, not in AppData or Documents. Each campaign, science or sandbox game is a subfolder with a persistent.sfs file.
Install-relative saves mean Steam reinstalls and moves can strand campaigns. Copy the folder out before touching the install.
Where Kerbal Space Program stores this, by platform
C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program\saves
One subfolder per saved game with persistent.sfs inside. Training scenarios and shipped crafts sit alongside. Copy the whole saves folder before reinstalls or moves.
Frequently asked questions
How do I back up KSP campaigns?
Copy the whole saves folder. Each save is a subfolder with persistent.sfs plus ships and training states. Restoring means dropping it back into a matching game version.
How do I share a ship design between saves?
Copy a ship .craft file from Ships (SPH or VAB) in one save into another save's Ships folder. Restart the game and the craft appears in the right editor.
