If you want to move media files from your PC to to the 8300 SD card, you can simply enable Mass Storage on your SD media card, and then move the files from your PC to the media card by dragging and dropping after you open the media card in "My Computer" on your PC. How do I add media files to my microSD card? - BlackBerryFAQ
yes, the above is the best way to move files to the card. I found Roxio to take A RIDICULOUS amount of time to even boot, let alone transfer any files... Using Mass Storage Mode is much faster...
If you go to the Blackberry downloads page for your device/carrier, you should be able to download the Blackberry Desktop Manager WITHOUT Roxio... I recommend you do that as well...
