REM file extension - BlackBerry encrypted data

What is rem file? How to open rem files?

File extension rem is most likely best known for its use in BlackBerry smartphones.

A .rem file can actually be any file format, but the rem file suffix signalizes, that the file is encrypted using the BlackBerry smart phone.

The files can be decrypted only with password used in the BB smart phone, or by the same password in the BlackBarry Desktop Software.

Example. "picture_name".jpg.rem

This rem file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
