Can I move my AppData folder in Windows 10?
Just moving the folder is not enough.
Once you have moved it, you must replace the original with a symbolic link to the new location. This will make windows think the data is still located on your C drive, while it actually is on your D drive.
Do note, this does work with AppData, but not with Program Files nor with the Windows folder, as it will break things like Windows Update.
To create the Directory Junction (Symbolic Link) do the following:
- Open a cmd window with administrative privileges.
- Navigate to c:\Users\username\appdata
- execute the following command:
mklink /d local d:\appdata\local
replace d:\appdata\local with the actual path of where you moved the appdata to.
If you cannot move/delete the original copy, create a 2nd user, make it administrator, login with it, and retry the option. This should ensure that no files are in use.
AppData folder has three folders inside and each can be moved separately.
Right click -> Properties -> Location.
