Er ... this indicator shows how many files you are sharing. On start up it increases in number until all your shared files are loaded. If you add more shared files via the Limewire Library, they will not load or show up on the counter until you press refresh. If you add them via preferences/options, they will not show up or dissapear until you press apply. When you do this the count returns to zero briefly, before counting up to the new number and uploads can be disturbed, temporarily. Removing files from share (not deleting) works the same way
I hope this helps, as your question was not totally clear
