Why would you wanna?? You never told us what the files are. If they are dud downloads from LimeWire, go for it. If they are from a program you KNOW you deleted, go for it. Operating system files, AT YOUR OWN RISK. Temp files may contain hidden files for programs you are using.

But Number One Rule is----if you have to ask, leave them alone. This is one of them cases where, what you don't know can hurt you.
