.CNB File

The cnb file extension is associated with Pegasus Mail, an e-mail client for Microsoft Windows and other platforms, developed by David Harris.

The cnb file contains mail messages stored in noticeboards.

How to open:

Use Pegasus Mail to work with *.cnb files.

How to convert:

As far as we know, this .cnb file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
