I cannot believe I haven’t written about this application yet.  This one is a must have it makes syncing and backing up a snap and also allows you to setup remote backups to FTP and allows you to run schedules.  I use this application once a week to copy my important files from my laptop to my backup hard drives.  I also use it to backup my pen drive (lesson learned there) and to sync 2 external hard drives with all my music as well as syncing my music folder with my girlfriends laptop.  Super easy to use and the price is right….FREE!
