If you use it reguarly it can be a real pain in the butt. The CDs, once written, have to be erased before new files can be written. The CDs have to have a name. When erased, they lose the name as well so the CD is a new, writable platform. Fortunately, this isn't a problem where I sit.
The other side of it is when I have multiple small files to transfer and a floppy isn't available, using FTP to/from my site is still faster and more efficient than the CD. But I have some rather large database and spreadsheet files where the Roxio CD manager is just great.
Other than that, all goes well. Without any other experience with anything other than Roxio, Roxio works as well as can be expected here.
