# Mass Extension Changer
# Coded by Zane ZenOokami Blalock

# This program essentially takes in your entered directory and changes any specified extension
# with another extension specified.

# Feel free to fork this project and make what you will with it, we simply ask that you give credit, and link back
# to our source location at our site (EssenceOfZen.org) and our GitHub. Thank you <3
