I'll give it a go, its mainly all just a recovery of a WinXP hard drive, they want the pictures on CD's(5 or 6 in all I think) of all things, so I need to pair it down some. I think one I get down to...

Mmmmmm command line should be able to select a wild cards, tho I am unsure if you can string them together. Not sure if you can exempt this and delete that and keep folders but delete empty folders...

Got an odd request, anyway to delete everything but picture files from a directory structure ?
