Can't remember seeing this little tip, but I'm sure its popped up a few times.
Ever been downloading some huge 700mb file (ssshh i'm on 56k and it takes ages) and then accidently canceled the download and you've lost it all? Happened to me a few times, but there is a way to backup your download so if you do cancel you just resort to the backup, you might lose some but not as much without a backup.
Its really easy, just make a new folder somewhere, call it something useful like download backups. Then copy your download, plus all the contents of the folder /kazaa lite/db/ into that new folder.
If you accidently cancel, just copy everything from that new backup folder to their proper place and your download is saved.
