The pm4 file extension identifies documents created by version 4 of Adobe PageMaker, Adobe's desktop publishing program for producing formatted publications.
A pm4 file contains a PageMaker document, including its page layout, text, formatting, and graphics information.
Adobe PageMaker was available for Microsoft Windows and Apple Mac platforms. The format is obsolete because PageMaker is discontinued, although the original application or a suitable legacy environment may still open these files.
MIME type:
application/x-pagemaker
Open a pm4 file with Adobe PageMaker version 4 or another compatible version of PageMaker. Use the Windows or Mac version that matches the environment in which the document was created.
Because PageMaker is obsolete, it may not run on a current operating system. A legacy computer or compatible older system may be required.
If PageMaker can open the pm4 file, use the application's export options to create a format supported by the installed software.
Check the converted document carefully, because obsolete PageMaker layouts may not reproduce exactly in other applications.

Pegasus Mail, developed by David Harris, is an email client for Microsoft Windows. A PM4 file stores the program's general filtering rules, which define how Pegasus Mail handles messages that meet specified conditions.
This is a Pegasus Mail settings file rather than a document intended for independent use. It belongs to the program's filtering configuration and is read by Pegasus Mail when the relevant mail settings are used. The format is specific to Pegasus Mail and is not a general-purpose data format.
Open a PM4 file through Pegasus Mail on Microsoft Windows. The file is normally used by the program as part of its filtering configuration rather than opened directly from File Explorer.
If Pegasus Mail does not recognise the file, it may not be in the program's expected configuration location or may belong to a different Pegasus Mail installation.
A PM4 file cannot usually be converted to a common file format because it stores Pegasus Mail filtering settings. To move the rules, use Pegasus Mail's own filtering or configuration features when available, or recreate the rules in another email program manually.
