Ever had to deal with several sprite packs that each have a couple hundred items in them, but have the same names? Bah! Dealing with that is such a hassle.
Well, that is unless you use this tool.
This tool will allow you to select a list of folders to look for files in (Warning: it will take -ANY- file from -ANY- subfolder) and enumerates them in a neat and orderly list starting to count from a number of your choosing. The result will then be copied to a new folder for you to use in your project.
If for whatever reason you want the source, it's on GitHub
