If you’re having trouble with the location of your .minecraft folder, or, want to move it to a different drive, you will need to change the Minecraft working directory.
Windows 10
Step 1
If you don’t have a shortcut to the Minecraft launcher on your desktop, open the Minecraft launcher folder, right click MinecraftLauncher.exe, choose Send to, then Desktop (create shortcut).
Step 2
Go to your desktop, right-click the MinecraftLauncher.exe – Shortcut and click properties.
Step 3
At the end of the Target field, add: --workDir file-path. Replacing file-path with the path to your new location.
Step 4
Click OK to save the changes.
Remember:
If you need to access your .minecraft folder, you must go to the new location. Your old.minecraft folder in %AppData% will no longer work.
