File type specification:

The pmm file extension is associated with the Pegasus Mail, the e-mail client for Novell Netware, MS-DOS and Microsoft Windows.

These file pairs reference actual mail folders, where messages are stored in a more compressed form. The former indexes the position of the message in the latter file.

The pmm file is a normal ASCII file containing all messages, separated by a CTRL-Z. Although this are ASCII files, any editing can mess up the folder content, making it impossible to access any individual messages. The above does not apply to the New Mail folder.

That folder is just a view on files with a CNM extension.
