Your mobi2mobi.exe file should be in the same directory as the books you want to rename unless you add a path for mobi to your system file. The only nice thing about using numerics in the title is that they sort first. I use 1 for library books and 2 for Kindle store books, 3 for free books, 4 mobileread books, etc. Then I can use alt+numeric to go to the beginning of that section.
Ohhhh, gottcha. I was thinking you were numbering your books 1-100.
Your idea is much better than mine.
Thanks for the mobi2mobi hints. I'll backup my files (again) and practice on some of the freebies first.
