I am using a computer with Windows XP on it. It's divided into 3 ntfs partitions. I would
like to install Fedora Core release 5 on this
computer. I don't want to dual boot with Windows. I
want to install Linux over it and erase it. I'm using
a 120 gb harddrive. There is music and some movies iso
files that I want to keep (about 20-30 gb). How can I
install Linux without losing it? I do not have an
external harddrive or other device to save to. 20-30
gb is too much to save to cds, and the isos have to be
burned to dvd. I want to install Linux and have my
music on there. Is there a way to do it without some
special equipment that I don't have?

You're going to have to create a new partiton, Fat32. From within XP, your size limit for Fat32 is 32 gigs so that's as big as it can be. Let's say that winds up being Drive F:.

Format all the remaining Windows partitions, turn them into free space, and install away. Linux will be able to recognize the Fat32 partition after it's up.
