Move your instances to JustLauncher
JustLauncher finds instances from 10 Minecraft launchers on your computer. Mods, worlds and settings move along with them. If a launcher is installed outside its default folder, you can point to it by hand.

How to import in 3 steps
- 1Install JustLauncher and open the instance list.
- 2Press «Import instances» and pick «From another launcher» or «From an instance file».
- 3Tick the instances you want and press «Import». Each one shows how many mods, resource packs, shaders and worlds it holds.
If an instance did not import
- Not installed
- JustLauncher did not find the launcher in its default folder. Press «Choose folder» and point to where the instances are.
- Not supported
- This version of the launcher stores instances in a format JustLauncher cannot read yet. Create the instance again and move the mods and worlds by hand.
- Imported incompletely
- The instance appeared, but not all of it was copied. Check that the disk has enough space and that you can access the folder. Delete this instance before importing again, or you will end up with a second copy.
- Missing mods
- In older Legacy Launcher instances some mods sit in the shared libraries folder instead of mods. That is why the old instance's mods folder does not show them, but JustLauncher imports them from there too.
