ECHO Google Drive FS - Silent Change Mountpoint Utility v0.0001
ECHO ----------------------------------------------------------

REM Scripted: Marc Vandael - 25/01/2018
REM Change the var _mountpoint to whatever driveletter you would like. 
REM If the letter is in use, the next free one will be used.
REM This attempts to write to HKLM & HKCU so admin rights are needed for this to work.
REM If you run this without admin rights, only the local user is affected.

SET _mountpoint= M

REM Add the magical REGkey

reg add "HKLM\SOFTWARE\Google\DriveFS" /v DefaultMountPoint /t REG_SZ /d %_mountpoint% /f
reg add "HKCU\Software\Google\DriveFS" /v DefaultMountPoint /t REG_SZ /d %_mountpoint% /f

REM End the DriveFS process

taskkill /f /im GoogleDriveFS.exe

REM Launch the DriveFS, forcing it to read the new mountpoint from the registry. Since the exe itself is located in a variable
REM folder (folder includes version number) I had to use the following... If anyone knows a more elegant approach, contact me.

FOR /F "tokens=* USEBACKQ" %%F IN (`where /R "C:\Program Files\Google\Drive File Stream" GoogleDriveFS.exe`) DO (
SET var=%%F
)

start "" "%var%"
