I install all my GOG games into a folder on my D drive, but I also install all my Steam games into a separate folder on the same drive. My problem is space I have very little left on this D drive, so I created another Steam drive folder on my F drive and no problems it was recognised by the Steam client and displayed with all my other Steam games. But GOG Galaxy does not recognise the extra Steam folder on the F drive so it does not display these games.
I also need to create another GOG folder on the F drive to install any new GOG games that I purchase, but I don't know if GOG Galaxy will recognise the new folder and display the extra games?
Is there a setting in GOG Galaxy that will allow the extra folders to be seen in the client?

Thanks for any advice!
