You can not usually make or delete a folder (album). There are some default folders: camera pictures, all pictures, photos, wallpaper. EXCEPT: you can make a folder, 'scrapbook', using the 'scrapbook app' (If you delete all the photos in that folder you delete the folder). I suppose there are other apps that are capable of making folders.
You can add photos and delete photos by USB to your PC
You can delete photos (and videos) on the PB:
pictures>select folder>drop down top task bar>edit>click the box on photos to delete>delete>'delete selected picture?'>delete
