Big problem with duplicate file names!

We have just installed our new vault and I am ready to do abulkcheck-in.  Unfortunately we have an existing filenamingconvention that permits duplicate file names (we use the'Number'field to differentiate various versions).  Iunderstand thatthe vault does not allow duplicate file names, evenif they are indifferent projects.  What is the best way tohandle this,keeping in mind there are too many files torename/fixreferences by hand?  Has anyone had thisproblem andfound a solution?SolidworksWorkgroup Pdm
