This Windows PowerShell script takes an inventory of one folder and for each file that exists will execute a delete in another folder. I wrote this to deal with some bizarre node/gulp race conditions while doing image optimization. So if a file has been processed (compressed) it is ok to delete it from the images_in folder.
