**Function:** Compares the contents of any two folders and returns matching or unmatching files.
**Author**: [Ben Long](http://www.completedigitalphotography.com)
**Input**: (Files/Folders)
**Output**: (files/Folders)
**Notes**: Compares any two folders and outputs your choice of all matching files, only matched files from either folder, or only different files from either folder. Also provides an option for ignoring extensions. I find this useful for comparing folders full of original images with folders of dupes that I've made and edited. The ability to ignore extensions lets you easily compare file names without worrying about whether you're looking at JPEG, Photoshop or raw versions.
