Sandman, most people use ABC in conjuction with a converter. Either in a program like ABCExplorer or EasyABC or in an internet converter like

http://www.mandolintab.net/abcconverter.php

All of these convert the ABC file to notation.

It's not really a case of ABC or notation. The ABC file is a means of storing and/or generating notation. I suppose some people can look at an ABC file and hear the tune. Most people won't even try. The ABC files are minute compared with files generated by Notation Editors like Sibelius and Musescore. There are great collections of traditional tunes in this format on the net and their small size makes them well used and well usable.
