How to open .MS files on Linux
To open .MS files on Linux, view/edit the .ms source in any text editor (it is plain text).
Step-by-step instructions
- View/edit the .ms source in any text editor (it is plain text).
- Render it with groff using the ms macros (see groff_ms(7) and the groff manual) to generate output such as PostScript/PDF, then open the result in a viewer.
Common issues
The file opens as “garbled text” or looks unformatted
.ms is typically roff source; it is meant to be processed by troff/groff with the ms macro package, not displayed as a finished document by default.
- Open it in a plain-text editor and confirm it contains roff/ms macros (lines starting with '.' or ''' are common).
- Render it with a groff/troff toolchain using the ms macros to produce PDF/PostScript for normal reading.
Rendering fails or output looks wrong
Formatting depends on using the correct roff implementation and macro package; missing macros or mismatched tools can cause errors or odd layout.
- Ensure you are using groff with the ms macro package (consult groff_ms(7) for expected behavior and options).
- Check the document for macros or requests that require specific preprocessors or a particular roff environment, then re-render.
Wrong app is associated with .ms
On some systems, file associations can point .ms to an unrelated program, causing confusing errors when double-clicking.
- Open the file explicitly with a text editor to confirm it is a troff/ms source document.
- Change the file association to a text editor (for editing) or use a rendering workflow (groff to PDF/PS) for viewing.
Security note
.ms files are plain text, but roff/groff is a powerful document processor; avoid rendering untrusted .ms files in automated pipelines if you are concerned about parser/toolchain vulnerabilities.
