I have a very large library (with many folders and subfolders) already created for my own use and stored on server. I now want to share that library with a new group, but every time I create a new group it creates a new library, and I see no easy way to transfer the old personal library into the new library without painstakingly re-populating the new group library with my old personal folder structure and dragging individual files from old library into new (and even there I'm encountering problems).

Is there a way to just give my group access to my original library? It seems like such an obvious and necessary functionality, but I see no way to do it! THanks!
