At work today, I was stuck with a situation in which I had to rename the extension of 250 files from .movie to .tga
I stumbled across this app today (freeware) that saved me 30+min of retyping file extensions.
Aside from renaming extensions, this app has about 10 other renaming options. It's extremely robust, and beyond useful.

rename *.movie *.tga
and save as rename.bat and run in the folder full of .movie files
i'd go with programs with big interface buttons and happy colors any day of the week
It has a whole slew of options. You can add or remove a single character (or more), add characters in - LOTS of stuff
