Does anyone know of a freeware renaming utility either preferrably with a GUI, however a DOS window'd app will do that can recursively look into hundreds of directories and properly rename well over 15,000 files from for example:
The Quick Brown Fox.txt
to
TheQuickBrownFox.txt, or The_Quick_Brown_Fox.txt
I need such a program because my mother has 1000's of sewing designs on a separate partition on my system that need to be archived onto a CD-R, and my two CD writing software packages belch about the filenames. Archiving in RAR, ACE, etc., is not an option since the files need to be accessable from the CD.
