I've got a good amount of music and other files on my computer that I really need to backup. About half of these files, I already have on my 15GB mp3 player/external hard drive because I backed them up a while ago. Is there any way to send all my stuff from my computer to the external hard drive and have them merge? I really don't feel like going through and picking out the ones that I need to send over and the ones that I don't. I noticed that when I send something that already has the name filename, a dialogue box comes up asking whether I would like to replace it and I can answer yes, yes to all, no, or cancel. Why can't they have a "no to all"? Is there maybe a program out there that will sychronize the files for me? I looked in some different places, but couldn't seem to find one. Any suggestions would be greatly appreciated. Thanks.
