Since I build website in a silo style sometimes, I put all of those website in a folder under my "All Projects".  I also have a folder that says... "Completed Projects 2017".  I would like to be able to make sub-folders under regular folders so I can move my silo sites under my "Completed Projects 2017" folder.  Also, you need to be able to place regular folders under any folder in that "All Projects" work space.  Thank you for your time!!!
