I downloaded: WotL 0.01d (Unfinished).rar
The file name of the map after I extracted the zip file was: 'WotL 0.01d WotL 0.01d (Unfinished)'
That's over 28 characters so I had to shorten the file name so that it would appear in-game.
I am using the lastest version of Wacraft 3 and unfortunately when I press 'Start Game' the map does not work so I cannot test it yet.
I look forward to testing though
