Renamer
I hate renaming files in windows. After shooting 200 pictures on vacation with my family I end up with a folder that has 200 files names IMG_0103.jpg. What I want to do is a rename so something a little more meaningful – Something like Vacation_to_India_2008_Pic_0103.jpg. Doing this in Windows can be a pain. Renamer is a free tool that solves this issue. Renamer allows to change case, modify names, and remove or replace strings in file names.
