Anyone out there use any file rename/file managment utility programs? I am looking for any input/opinions from fellow CAD gurus.

My workstation crapped out last Monday & I know have the delight of installing and reworking my new workstation. I am now on Windows 7 64 bit. I did use a free version of "Better File Rename". It wasn't too bad to use. I've been trying to read through all the reviews.
