Where Does Prism Launcher Store Instances?
Prism Launcher instances, saves and settings paths on Windows, macOS and Linux, including the Flatpak data directory variant.
Last updated
Prism Launcher keeps every modded setup as an instance folder with its own .minecraft, saves, mods and Java settings. The parent folder is called PrismLauncher and sits in the usual per OS data directory. Worlds live inside each instance, not in the vanilla Minecraft folder.
That separation is the point. Vanilla saves stay untouched while instances carry their own mods. To move one setup, copy its single instance subfolder. To move everything, copy the whole PrismLauncher data folder with the launcher closed.
Where Prism Launcher stores this, by platform
%appdata%\PrismLauncher\instances
Each subfolder is one instance with .minecraft/saves inside. Settings live in prismlauncher.cfg one level up. Portable builds use an instances folder next to the exe instead.
~/Library/Application Support/PrismLauncher/instances
Use Go > Go to Folder in Finder. Worlds are at instances/[Name]/.minecraft/saves. Copy the instance folder to share a pack with its saves intact.
~/.local/share/PrismLauncher/instances
Flatpak installs use ~/.var/app/org.prismlauncher.PrismLauncher/data/PrismLauncher/instances instead. Config sits at ~/.config/PrismLauncher on native installs.
Frequently asked questions
Where are my Prism Launcher worlds?
Inside instances/[InstanceName]/.minecraft/saves, one folder per world. Copy the world folder into any other instance's saves folder to reuse it with a different mod set.
Can I change where Prism Launcher stores instances?
Yes. Open Settings > Folders and change the instance path, then let Prism move the data. Keep it on a local drive, since network paths break mod loading and game startup.
