The default storage location of the myCloud folder is within the user directory. This prevents other users on the same computer from accessing your data when they use other user accounts.
You do, however, have the option of storing your local myCloud folder in another location on your hard drive. This can either be done during installation or changed afterwards under “Settings” and “My profile”.
Please note that changing the storage location of your myCloud folder will cause you to be logged out of myCloud and you will have to set up myCloud anew.
For technical reasons, only local drives are supported. External devices as well as Network drives and virtual drives are not supported. You can learn more about this here.
