Go to Limewire options or preferences > Sharing > Shared folders, and here you can add or remove any folders you wish to share. This can also be done in Limewire Library but is easier in preferences.
WARNING if you use the limewire library ... On no account DELETE any shared files as they will be deleted off your computer without going to the trash/recycle bin and you will loose them!!!!
I hope this helps, and thanks for the files
