How to open .MIZ files on Windows
To open .MIZ files on Windows, right-click the .miz file → Open with → choose a text editor (for example, Notepad) to view it as plain text.
Step-by-step instructions
- Right-click the .miz file → Open with → choose a text editor (for example, Notepad) to view it as plain text.
- If you need to check/verify the article, open it in your Mizar setup and run the Mizar Verifier on the file (viewing alone does not validate it).
Common issues
The file opens as garbled text or with the wrong app
Some systems won’t recognize .miz automatically, or they may not associate it with a text editor.
- Manually choose a text editor via “Open with” and confirm the content is readable as plain text.
- On Linux, update/refresh shared MIME-info associations if needed so *.miz maps to text/mizar.
You can read the file, but you can’t verify/check it
Viewing a .miz file in a text editor does not run Mizar’s checking; verification requires Mizar’s tools (e.g., the Verifier).
- Install/use a Mizar environment and run the Mizar Verifier on the .miz file.
- If you’re on iOS/Android, move the file to a desktop system where Mizar tools are available.
Verifier/tooling errors on a .miz article
Mizar articles often depend on the expected toolchain setup and supporting environment; mismatches can cause failures even if the file is readable.
- Confirm you are using the intended Mizar tooling workflow and run the Verifier as documented for your setup.
- Compare the article to known-good examples of published .miz articles to ensure the file is complete and not truncated.

Recover a deleted or lost .MIZ file
If the file was deleted by mistake or the drive was formatted, data recovery software may be able to get it back. Stop writing to that drive right away, because new data can overwrite what you want to recover.

Security note
.miz files are typically plain text, so they usually don’t contain embedded “active” content like macros; however, treat them as untrusted input to specialized parsers (like verifiers/compilers) and only run Mizar tools on files from sources you trust.
