Map network drive for Google Drive to appears as a normal drive in Windows Explorer

No just a folder. Well you could use the subst command to map a folder as drive letter I guess. Haven't tested it, google drive might do something special, syntax wrong somewhere etc.

subst g: "c:\users\username\Google Drive"

Change "username" to your user name of course. Run at startup using a bat-file perhaps i autostart or similar.

I'm curious, why a drive, not OK with just a folder? Multiple users sharing perhaps? If so permissions might be needed to be set.

Update: I got curious and tried it and it seems to work.
