Tom,
I was just checking my notes, and just remembered that you can look up vault filenames using the wtcontenveryfy tool that comes with windchill:
From a Windchill Shell, run windchill wt.fv.tools.WContentVerify -user=<adminid> -password=<adminpassword> -checkBusinessObject
WContentVerify will prompt you for the Content Type of the object
Select Content Type :
1. WTDocument
2. WTPart
3. CAD Document
Enter 1,2, or 3 depending on the business object in question.
At the remaining prompts enter the objects Number, Name,Version and Iteration. For example,
Enter Document Number
GC000035
Enter Document Name
WHEEL_HUB
Enter Version :
A
Enter Iteration :
1
WContentVerify will create a summary report under Windchill\logs with the name BusinessObjectCheck_<date>_<time>.xml
Obviously the part has to be still in the system to find this information, though.
