Pegasus Mail draft outgoing message
File type: Various data file
Files with the pmw file extension contain outgoing messages saved as drafts for Pegasus Mail.
Pegasus Mail uses this extension instead of .msg for these messages because .msg conflicted with messages used by Trumpet Winsock.
Found 3 different file type records with the same pmw filename suffix.

The pmw file extension is associated with Pegasus Mail, an email client for Microsoft Windows. A PMW file stores an outgoing message in draft format so that it can be reviewed or edited before it is sent.
This file type replaced the msg extension in Pegasus Mail because that extension conflicted with Trumpet Winsock messages.
In Pegasus Mail, PMW files are handled as queued mail. The messages can be accessed through the File | Review queued mail menu entry.
Open a pmw file with Pegasus Mail on Microsoft Windows. In the program, use File | Review queued mail to review and edit the stored outgoing message.
A PMW file is an internal Pegasus Mail draft format and does not have a useful standalone conversion. Open it in Pegasus Mail to edit or send the message, or copy its contents into a message in another email program if necessary.

The PMW file extension identifies the proprietary spreadsheet format used by PlanMaker 97. A PMW file can contain worksheet data, formulas, and cell formatting for use in the application.
PlanMaker is developed by SoftMaker and is available for Microsoft Windows as part of SoftMaker Office and as a standalone application. PMW is a legacy PlanMaker format, although current versions of PlanMaker and compatible office suites may still provide support for opening it.
On Microsoft Windows, open a PMW file with PlanMaker, SoftMaker Office, or Ashampoo Office. PlanMaker Viewer can be used when the file only needs to be viewed.
If the file does not open by double-clicking, start the spreadsheet application first and use its Open command to select the PMW file.
Open the PMW file in PlanMaker, SoftMaker Office, or another compatible office suite and use Save As or Export to create an Excel-compatible spreadsheet file. This is usually the most practical way to move the data to a newer format.
Exporting to CSV can preserve basic tabular data, but it does not retain the workbook's formatting and may not preserve formulas. The original PMW file should be kept if those features are needed.

Record marked as obsolete and not updated for a long time.
The pmw file extension is associated with Windows Performance Monitor, a Microsoft Windows utility for analyzing system performance.
A pmw file contains a workspace used by the Windows NT version of Performance Monitor. The workspace preserves the utility's monitoring setup so it can be reopened later.
This format is associated particularly with Microsoft Windows NT 4.0 and is now obsolete. Current Windows versions may not support these legacy workspace files.
Open a pmw file with Windows Performance Monitor on a compatible Microsoft Windows NT system. In Performance Monitor, use the command for opening an existing workspace and select the file.
Modern Windows versions may not open this legacy format correctly. If the file is important, use an appropriate older Windows NT environment rather than renaming the file or opening it with an unrelated program.
The obsolete pmw file format stores a Performance Monitor workspace rather than a general-purpose document or performance-data file.
If the file can be opened in a compatible version of Performance Monitor, reproduce its monitoring settings manually in a current monitoring tool. This does not directly convert the original workspace.
