How to open .SAM files on Windows
To open .SAM files on Windows, check the file properties and confirm it is a Lotus Word Pro/Ami Pro document (often associated with application/vnd.lotus-wordpro).
Step-by-step instructions
- Check the file properties and confirm it is a Lotus Word Pro/Ami Pro document (often associated with application/vnd.lotus-wordpro).
- Try opening it with software that supports Lotus Word Pro documents (legacy Lotus/IBM-compatible office software).
- If it still won’t open, use that software’s export/save-as feature to convert it to a modern format and then open the converted file.
Common issues
No app can open the .sam file
Many modern systems do not include software that can read Lotus Word Pro/Ami Pro document formats.
- Try a desktop environment where Lotus Word Pro-compatible software is available, then open and export the document to a modern format.
- If you are on macOS/iOS/Android, plan on conversion on a desktop first (then view the converted file).
File is misidentified or opens as the wrong type
File associations can be missing or incorrect; on Linux, detection may rely on shared-mime-info mappings and signatures.
- Verify the extension is actually .sam and that the file came from a Lotus Word Pro/Ami Pro workflow.
- On Linux, update your shared MIME database and retry opening, then explicitly choose an appropriate document application if available.
The document opens but text/layout is garbled
Legacy word-processing formats can depend on fonts and older layout rules that do not translate cleanly in importers/converters.
- If possible, open the file in the original/most compatible software and export to PDF for faithful layout.
- Try a different import/conversion path and compare results (PDF export is often more consistent than editing formats).
File appears corrupted or incomplete
Older binary document formats are sensitive to partial downloads, email-gateway modifications, or storage damage.
- Re-copy or re-download the file from the original source and compare file sizes.
- If you can, test-opening it on a system known to handle Lotus Word Pro documents to rule out a local issue.
Security note
Treat .sam files as untrusted input when they come from unknown sources: they are complex legacy document formats and have historically relied on older parsers that may not be hardened.
