Prepend is a command line program to add a string to the beginning of all files in the directory it is called in. 

Directions:  Add Prepend to your PATH.  Navigate to the directory containing the files you want to rename and run Prepend as follows

prepend "string to prepend to filenames"

Notes: This program was tested with Ruby version 1.8. The .exe, however, does not need any version of ruby installed.
