[hyperlink] How link to any local file with markdown syntax?

Thank you drifty0pine!

The first solution, it´s works!

[a relative link](../../some/dir/filename.md)
[Link to file in another dir on same drive](/another/dir/filename.md)
[Link to file in another dir on a different drive](/D:/dir/filename.md)

but I had need put more ../ until the folder where was my file, like this:

[FileToOpen](../../../../folderW/folderX/folderY/folderZ/FileToOpen.txt)
