Need help administering files in Workgroup PDM library

Hi all,

I've inadvertantly moved and assembly into my workgroup PDM library.  In the process of doing this I've deleted the original files from my HDD.  I don't seem be be able to either get the files copied back to my HDD or make any changes necessary to get them moved.  Is there any other way to access the vault?  I've attached a picture of my vault tree for reference.
