We are currently running PDM Workgroups 2012 to manage our models and drawings.  During our learning stage we added a point library in PDMWorkGroups.  That directory no longer exists, but the library folder does.  Having the folder in vault causes confusion and should be deleted.  Many of the part are no longer available.  What is the best (easiest) method to delete unused library folders?

Thank you in advance,

David Tg
