I can't open media files
Try the following actions:
• If you're trying to open a media file on your BlackBerry smartphone and your smartphone is connected to your
computer, disconnect your smartphone from your computer.
• If you encrypted the media files on your media card using an encryption key that your BlackBerry smartphone
generated and you're trying to open an encrypted media file on your computer or a device other than the BlackBerry
smartphone that you used to encrypt the file, insert the media card into the BlackBerry smartphone that you used to
encrypt the file. On the home screen or in a folder, click the Options icon. Click Security > Encryption. In the Media
Card section, change the Mode field to Device Password.
• For more information about synchronizing media files, see the Help in the BlackBerry Desktop Software.
