In short: WinRAR treats .md as a plain-text file — select it inside an archive and press Enter or the internal viewer to read it without extracting. It shows the raw Markdown source, not a rendered page.

WinRAR Markdown Guide

Preview, bundle and document with Markdown (.md) files

Markdown (.md) is just structured plain text, so it works smoothly with WinRAR’s built-in viewer. For power users this means three practical things: reading documentation inside an archive without extracting it, bundling a README with what you compress, and keeping plain-text notes via archive comments.

Good to know: WinRAR does not render Markdown into formatted text — it shows the raw .md source in its built-in text viewer. That is still useful: you can read a README inside an archive without unpacking it, and ship documentation alongside your files.

What you’ll need

How to work with Markdown in WinRAR

1

Preview a .md file without extracting

Open the archive in WinRAR, select the .md file, and press Enter (or right-click → View file). WinRAR’s internal viewer shows the raw text instantly — handy for checking a README before unpacking.
2

Make WinRAR always use its text viewer

Go to Options → Settings → Viewer and choose Internal viewer (or set an external editor). This controls what opens when you view a .md or other text file inside an archive.
3

Bundle a README.md with your files

When creating an archive, simply include your README.md alongside the content. Anyone who opens the archive can read it in place — a clean way to ship instructions with a download.
4

Use the archive comment for quick notes

WinRAR can store a plain-text comment inside the archive itself: Tools → Archive comment (or the Comment tab when creating it). It is plain text, so you can paste Markdown-style notes there as a lightweight changelog.
5

View the comment later

Open the archive and use Tools → Show information or the comment pane to read the stored notes. Comments travel inside the archive, so they sync and back up with it.
6

See the formatted version when needed

For a rendered preview, extract the .md and open it in a Markdown editor or browser extension. WinRAR’s role is fast in-archive reading and bundling, not formatting.
