CollapseAdditional Information

Media files that are already on the device at the time Media Card Encryption is enabled will not be encrypted. Only newly saved media files will be encrypted. Additionally, media files that are encrypted when Media Card Encryption is disabled will remain encrypted.

Encrypted media files can only be viewed on the device.  When viewed on the computer while the device is connected via USB, it will show a .rem extension (such as filename.jpg.rem).  Roxio Media Manager for BlackBerry smartphones is able to transfer media to an encrypted media card and decrypt media when the file is transferred back to a computer. This will remove the .rem extension on the transferred file and allow it to be accessed by the computer. The copy on the media card remains encrypted.

If all data and applications have been deleted from the BlackBerry smartphone and Media Card Encryption was set to Device Key, the BlackBerry smartphone will no longer be able to access encrypted files. The following error message will appear:

Unable to display file filename.jpg.rem

This is by design as a security measure.
