xmp Files

One of my folders, “Olympus Stock”, which contains extra pictures I haven’t worked on, is about to reach 70 GB, which will be too big to burn on a single CD. So I started looking up external hard drives I could buy from Wal-Mart, and there’s one I could afford for $50.00 and it has 500 GB of space. There’s also another folder that could be burnt on a CD but it also contains xmp files. I don’t know what those are but should I delete them or? I am going to buy the hard drive when I have the money because the computer has been running slow for a few days and there are still more pictures coming so I want to clear up room for the rest of them.
