Multiple files in PDMWorks Workgroup vault

I am using SW2009 SP3 and PDMWorks Workgroup. When I look atmy log file I get the following message for multiple componentswhile the vault is validating "05/07/2009 15:35:57pdmwTreeInfo::Build() -- ERROR: Document 86026-X2.SLDDRW in project5175 - NL & HW CHAIN SHIELDS already exists in anotherproject." If I search the vault directory on the server there aretwo files found under two different projects. I did not think thiscould physically happen.SolidworksWorkgroup Pdm
