When sharing it allows you to share folders, sub-folders, and files. When unsharing only able to unshare folder, thus unlisting it entirely from the library. You can individually open each folder and unshare files this way keeping the folder listed in the library, (lot of work with large quantity of files) But A nice feature would being able to unshare files however selected and still see the folders listed in the shared file column. (My preference because I like the way the limewire library is set-up.) I could leave them shared always to solve this, but seems like the request may be simply done? If could be done I would be more apt to share more files, knowing at my desire I could easily unshare them with a lot less work!
