When you download MP3 files to a BlackBerry, the file name may be appended with the .REM file extension. If the .REM file extension has been appended to the file name of an MP3 file, this indicates that the file is encrypted. Converting the .REM file to its original format is not quite as simple as just deleting the added .REM extension. You must decrypt the file to restore the original format.
How BlackBerry Encryption Works
If you download a song with the filename of LittleStar.mp3, a second file extension is appended to the filename, so the filename becomes “LittleStar.mp3.rem.” The .REM file extension indicates that the file is secured with BlackBerry’s proprietary encryption code. To convert the REM file back to its original state, decrypt the drive where the MP3 file is stored. Once encryption is disabled, all original file names and extensions are restored. If the MP3 file is stored on the device’s internal memory, decrypt the internal drive. If the MP3 file is stored on the SD card, decrypt the memory card.
Decrypt All Data
Decrypt the internal memory or SD card to remove the .REM file extension from all files saved on the card or phone, not just the MP3 files. To decrypt the phone’s SD card or internal memory, tap the “Options” icon in the BlackBerry home screen to open the Options menu. Tap the “Security” tab, then the “Encryption” option to open the Encryption settings screen. Tap the “Encrypt" check box in the Device Memory section to uncheck the option and decrypt the phone’s internal memory. Tap the “Encrypt” check box in the Media Card section to deselect the option and decrypt the SD card. Tap the Back arrow, then tap “Save.” The settings are saved on the device.
Decrypt Only Media Files
You can decrypt only images and media files stored in internal memory or on the SD card, leaving other sensitive data encrypted. Open the Encryption Options menu on the device, then tap the “Include Media Files” check box to deselect the option in the Device Memory and/or the Media Card section. Tap the Back arrow, then tap “Save.” The settings are saved on the device.
Share or Transfer MP3
Once the drive where the MP3 file is stored is decrypted and the file is restored to its original format, you can share or transfer the audio file as you would with any other file. You can connect the BlackBerry device to your computer, then transfer the MP3 file in its original format by dragging and dropping the file onto your computer. You can also email the file to yourself and other recipients, or share the file on social media.
