I have several *.CNM files.

How can I read the content with Pegasus Mail v4.63 ?

They appear automatically when they arrive or are placed in your new mail location for that user, by default c:\pmail\mail\admin

If moved or copied from elsewhere they must not be marked R (read only) attribute  at OS level.

Did you actually do read new mail button or from file menu?

.cnm files are just raw messages as received from the mail server complete with all headers and body  parts. One .cnm file per message.

.cnm files are new message files.  They reside in a mailbox directory (c:\pmail\admin for example) and are visible as new messages by Pegasus Mail.  If you have some .cnm files that are outside of a mailbox directory you can copy them to a mailbox directory and they will be visible as new messages.  You can also use the 'Add mailbox to list' feature to add the directory where the .cnm files reside as an added mailbox.  Finally, .cnm files are plain text files that can be viewed with a text editor.
