# Where Does Core Keeper Save Your World? (Core Keeper Save Location)

Knowing your Core Keeper save location matters whether you're backing up progress, recovering a lost world, or sharing your save file with a friend so they can continue on another PC. Since Core Keeper stores each world folder locally rather than in the cloud, your save data sits in a specific path tied to Steam and AppData, which is why players often run into trouble after reinstalling, switching computers, or losing an existing world without a backup.

## Local Save Files

* Navigate to the following directory locally: `C:\Users[username]\AppData\LocalLow\Pugstorm\Core Keeper\Steam[SteamID]\worlds`

* The `.gzip` files are the compressed world data files.

## Server Save Files

* Access the [Apollo Panel](https://control.sparkedhost.us/).

* To switch between worlds. Go to the **Startup** tab and adjust the "World Index" to match the world index number. In this example, the world file is `4.world.gzip` so we will set it to `4`
