How to open a .md file
A .md file is a Markdown document: plain text with a few symbols for formatting — # for headings, ** for bold, - for lists. Any text editor can open it, but you'll see those symbols. To read it the way it was meant to look, open it in a Markdown reader.
The quick way: install Rho MD (free), then double-click any .md file — or drag it into the window.
On Windows
- Install Rho MD from the Microsoft Store.
- Double-click the
.mdfile. If Windows asks which app to use, pick Rho MD and choose Always. Or right-click the file → Open with → Rho MD.
Without installing anything: Notepad opens it as plain text.
On Mac
Rho MD for Mac is coming to the Mac App Store soon. Until then, TextEdit opens a .md file as plain text, and pressing Space on it in Finder shows a plain-text preview.
On Linux
- Install Rho MD from the Snap Store (
sudo snap install rho-md), or the AppImage or.debfrom the download page. - Double-click the file, or right-click → Open With → Rho MD.
Any text editor — gedit, Kate, nano — opens it as plain text.
On Android
- Install Rho MD from Google Play.
- Open the
.mdfile from your Files app, a download or an attachment, and choose Rho MD.
On iPhone and iPad
Rho MD for iPhone and iPad is coming soon. Until then, the Files app shows a .md file as plain text.

That's all Markdown is: text you can read even without a reader, that turns into a clean document with one. Rho MD also renders tables, math, diagrams and code — and documents can include live charts you can drag.
Questions
How do I edit a .md file?
In Rho MD, click any paragraph and type — the document itself is the editor — or switch to the Markdown source at any time. Any text editor works too.
Can I convert a .md file to PDF?
Yes. In Rho MD on Windows or Linux, right-click the document and choose Export as PDF.
What's the difference between .md, .markdown and .mdx?
.md and .markdown are the same thing — Markdown. .mdx is Markdown with components for websites. Rho MD opens all three.
Do I need an account?
No. Rho MD works fully without an account, and your files stay on your device.
More than Markdown. Read, write, organize & focus — Rho MD is free.
