Yes thats what I had figured out myself.
What I want is the following:
I have a portal to my games folder. I installed all my games into that folder. For different reasons I have to access only 4 of my installed game folders regularly. The other 30 folders and files that are in this folder just make the portal unnecessary large as I only want a small portal which lists the before mentioned 4 specific folders. I obviously can't move the other folders somewhere else as this is still the folder all my games are and will be installed into.
It would be a good feature if I could tell the portal which files and folders it shows on the desktop and which it can just hide. In case I need one of the folders that is not listed in the portal list, I could still just open the original folder by double-clicking the title
