PNX files belong to Pegasus Mail, the email client for Microsoft Windows. They store the RTF representation of the message body so that formatting can be retained in a queued or draft message.
The base name of a PNX file matches the corresponding pmo, pmx, or .PMW file. A PNX file is therefore a companion file for a queued or draft message, not a complete message by itself.
PNX is an application support format used by the Windows version of Pegasus Mail. It is intended to be managed by Pegasus Mail rather than opened as a general-purpose RTF document.
Open the associated queued or draft message in Pegasus Mail on Microsoft Windows. The corresponding PMO, PMX, or PMW file is needed because the PNX file contains only the formatted message body.
Opening a PNX file directly may not display a complete message. Keep it with its matching message file and let Pegasus Mail manage it.
There is no need or usual method to convert a PNX file independently. Open the associated message in Pegasus Mail and use the program's available message editing, copying, or export options to obtain the content in another format.
