The Pegasus Mail IMAP message flag status file records the status flags associated with messages in an IMAP mail folder. It is a supporting cache file, not a message document intended for direct editing.
Pegasus Mail uses these files with its IMAP mail folders and the Mercury/32 mail system. The software is available for Microsoft Windows.
The file is managed internally by the mail software and generally has no useful standalone purpose.
Do not open the file directly as a document. It is an internal cache used by Pegasus Mail on Microsoft Windows while handling the related IMAP mail folder.
If opened directly, it may appear as unreadable cache data because it is not intended for manual viewing.
A .pnm file is an internal IMAP status cache and has no practical standalone conversion format. It should be managed by Pegasus Mail rather than converted manually.
