It is a tool to strip unused files from MV projects to get the filesize down. t's just a simple nwjs app. If you open the package.nw you can check out the code, improve it or whatever. I'll add a license later on if I find time -- probably MIT or BSD.
It errs on the side of safety, so if a file is referenced from anywhere in your project it is kept. #tool #utility #rpgmaker
