I need to know how to modify a file's properties. I've created a program that will temporarily place a different one in startup and because they're off a CD it's properties set it as ARCHIVE. Because it's archived I can't delete it. I need to know how to do this. The KILL function is what I've been trying to use. If anyone out there knows how to do this I really need to know.

Thanks in advance, Zaphod64831
