What is a PMO file? A PMO file is a project created by PrintMaster, a desktop publishing program developed by Broderbund. It stores the full project data needed to recreate a design, including layout details, text, graphics, and formatting settings. PrintMaster users create PMO files to save custom greeting cards, brochures, labels, banners, and other printed materials.
More Information The PMO format acts as a container for a completed or in-progress design. It preserves the page layout and references to the images and fonts used in the project. Within the Broderbund creative software suite, users can transfer PMO projects between compatible programs. Typical users include home users, small businesses, and hobbyists who create custom print materials for personal or promotional use. NOTE: In PrintMaster, you can export a project as a PMO file by selecting File → Export As .

A PMO file may also be a saved email message created by Pegasus Mail, an email client for Windows. It stores a single email message in plain text format, including message headers, recipient information, subject line, and body content. PMO files may also contain references to attachments, depending on how the user saved the message.
More Information
Pegasus Mail uses PMO files to store messages that users save manually or that the program saves automatically as drafts. These files allow users to preserve unfinished messages and reopen them later for editing or sending. Because the format is text-based, it is straightforward and designed for use within the Pegasus Mail environment rather than for general-purpose sharing.
How to open a PMO file
You can open PMO files with Pegasus Mail in Windows. Since PMO files store information in plain text, you can also view their contents with a standard text editor, such as Microsoft Notepad or Apple TextEdit . However, editing the file outside Pegasus Mail may affect how the program reads it.
