About transferring and synchronizing media files
You can connect your BlackBerry® smartphone to your computer to transfer and synchronize files between your smartphone and your computer using a USB cable, or you can use Bluetooth® technology to send media files to or receive media files from a Bluetooth enabled device.
When you connect your smartphone to your computer using a USB cable, the USB option that appears in the dialog box on the screen allows you to drag most files from a folder on your computer to a folder on your smartphone or media card. The media option in the dialog box allows you to transfer media files that are protected with DRM to and from your smartphone. Both options allow you to use the BlackBerry® Desktop Software to transfer files to and from your smartphone.
If you want to manage and preserve the information or the encryption that is associated with your media files when you transfer files between your smartphone and your computer, see the Help in the BlackBerry Desktop Software. To download the BlackBerry Desktop Software, from your computer, visit www.blackberry.com/desktop and select the appropriate option for your computer.
