The purpose of assigning a different Virtual folder from the Server-side path is for legacy applications that expect to find data in specific locations.
In the server-side path, %user_id% is the user's email. In the Virtual folder's path you can use: %Profile% %Common Profile% %AppData% %ProgramData% %Program Files (x86)% %Program Files%
Note that you must use the 'deepest' path variable. For example "%Profile%\AppData" is wrong, and should instead be "%AppData%".
