Notes about the REM file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The REM file type is primarily associated with 'Blackberry Desktop Manager / Blackberry devices' by RIM.
.REM files are Blackberry files that have been encrypted using the Blackberry device's encryption option. The REM extension is appended at the end ex <filename>.jpg.rem
Depending on how to device was encrypted you may or may not be able to open a Blackberry REM encrypted file. When Blackberry encrypts files it uses a randomly generated Device Key which is stored in its RAM. If the device is wiped or re-installed, RAM is cleared and the key will no longer be available.
If files were encrypted using a User or Device Password, this will be required to open a Blackberry encrypted REM file.
