each backuped document contains an unique number combine with the original name, showing as follow:

0atbhe70d50189ae5412186f546ee8099999_Term2.PDF
My question is that am i able to use those numbers to match to the corresponding module? In other words, the module those documents belong to.

Or is there other ways to match the module?

Thanks

John.
