About transferring and synchronising files
You can transfer and synchronise files between your BlackBerry smartphone and computer using a USB cable, or you can use Bluetooth® technology to send files to or receive files from a Bluetooth enabled device.
If you want to manage and preserve the information or the encryption that's associated with your files when you synchronise files between your smartphone and your computer, use the BlackBerry Desktop Software. To download BlackBerry Desktop Manager, from your computer, visit www.blackberry.com/desktop and select the appropriate option for your computer. For more information about synchronising files, see the Help in the BlackBerry Desktop Software.
