Hello has anyone run across a tool that will allow me to generate a cross reference index for all of the WORD and PDF documents in a given Microsoft C:/ directory?

I've been able to do it myself with a tool i created, but i first have to transform the WORD and PDF documents to .TXT files and i do that with another tool, but the the problem with this whole approach is i can only reference the .TXT files in the reference, not the actual WORD or PDF file word location references.

Thanks for any ideas or references to other tools!
