It will not display the folder itself, only the contents of that folder.

If you want to put it on Limewire as a complete folder, you will have to make a .zip or a .rar archive and put the files in there.

There are some cons by doing it like that. Many people tend to stay away from archives, because people can put anything in them. Also you will often end up with viruses when downloading them.

Another con would be that the entire content of that archive will have to be downloaded before you can play it. (no preview)
