Convert MWD to 4 (Man Page)

The MWD file extension stands for Mariner Write Document, a file format developed by Mariner Software for their streamlined word processor, Mariner Write, designed for Mac OS X. These documents can contain formatted text, graphics, headers, footers, and other data. While Mariner Write is no longer actively developed, MWD files can still be opened using compatible programs.

The 4 file extension refers to Unix Section 4 Manual Pages, which document special files and device drivers. These files, such as "mouse.4", describe how devices interact with the Unix operating system and are accessed using the "man" utility. Historically, these manual pages have been a fundamental part of Unix documentation, helping users understand and manage system devices.
