Before I OCR the files, I copy them and keep the original scan unchanged. I wanted a way to embed this original filename in the copy of the file, so if I ever needed to go back and find it I could. I tried hundreds of programs before I found one that worked:
A-PDF Rename

Filename:%Filename%_MT
Date:Scan %Date% %Time%
Author: %filename%%Filename%
Keywords: Scan OCR Fujitsu S1500 Scanned Scanner PDF
