Links to files that contains spaces

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.<br/><br/>

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.<br/><br/>

Example: [alt](my cool file.md) โฎ• [alt](my%20cool%20file.md).
