Make a Back up of your BIN folder ( Version 1.1.0.16 ) so you can go back to it if you like.
Then Install the New version 1.1.0.26
(use the Download page at the top of the website)
on the Advance screen of the Settings tab,
You can Now Choose the Location (any folder on any drive) where you want your collection to be Moved to.
After you choose a new location, you must Quit VG, then Restart VG.
on the Restart it will MOVE all of your Collection to the new spot.
You have 376 cards, so I think it will take a little bit of time ( 2 to 4 hours )
to move all of your cards to a new Location.
