Want to back up your iTunes library and/or transfer it to another PC? iTunes itself has a backup option, but it requires blank CDs or DVDs. Bleh.
CopyTrans TuneSwift will back up your iTunes library to the media of your choice (including network folders, flash drives, and external hard drives), or let you transfer it to another machine--Windows or Macintosh.
(Just to clarify, TuneSwift itself is for Windows only, but it includes an option for transferring iTunes libraries to Macs. Pretty neat!)
