Our electrical engineers use Siemens TIA Portal.  When they create their programming it creates a folder structure that has several files with different extensions among the folders.  The files this program creates are always the same.  Our vault does not allow same named files but if we change the name of their files to be unique their program doesn't recognize them.  We do want them to keep them in the vault so there is revision control.  From what I was told this was possible nine years ago when we had Workgroup.

Any ideas besides creating a separate vault that allows duplicate file names just for our electrical engineers?  Currently running SW17 SP2
