1. Unable to download the program from any links here or practically anywhere else, as links typically come up "denied" or "unable to find server." Eventually found a copy at Brothersoft.
2. Builds directories and stores files as per the tags/iTunes. In my collection this easily becomes messy, as a very large number of "artists" are unique (and I add files constantly in batches by their catalog number). Keeping original filenames in a single directory is much preferable. If something in the file scheme causes a duplicate name, simply adding a number to the end, like the Apple file system does, will work.
3. Seemed to work quite well until the failing iPod gave an I/O error, and then it just blew through all the remaining titles in a minute, copying blank folders and files to the destination directory.
This last needs to be corrected no matter what the source of error, as it makes the backup look valid, until you look at the file sizes. This is even more important when dealing with a failing iPod!
