The root folder of your files! Markor starts with this folder at the main screen and allows you to browse files. You can work at any (accessible) file & location with Markor.

Your main to-do list file in todo.txt format. You can access it by swiping once at the main screen, by selecting todo.txt at Notebook, or by using the dedicated launcher. You can also open it from Notebook or other apps! You will also have the option to create a to-do task when sharing text into Markor when the text is just one line.

Format: Markdown

What is Markdown?

A general purpose markup format for documents of all kinds. As Markdown gets converted to HTML prior displaying a rendered view, you can also include HTML in the text, thus you can do everything web browsers can do.

CommonMark is the specification that the markdown parser used in Markor implements.

Most Markdown applications use URL encoding for links, so does Markor. This means replace every space with %20. This ensures that your Markdown content is compatible with most other Markdown applications.

Markor has a dedicated button for adding links and file references, which automatically applies this appropiate format. Take a look at this video to find out where the file reference button is located and how to use it.
