What is a REM file
The REM file type is associated with the BlackBerry family of smartphones and devices. Files with the REM extension are files encrypted using a BlackBerry device and can be decrypted using the same. After the files are decrypted they can easily be transferred to a computer and opened in the usual way.
REM is used as a compound extension for the files encrypted using a BlackBerry device. The basic format for these files is "filename.extension.rem" for example if its a JPG file the encrypted version of the file would read as "filename.jpg.rem". The device uses a random key generation algorithm to encrypt the file and stores it in the device's RAM.
Here's a small, but not exhaustive list of programs that can open REM documents:
