I really don't know as the subject does not interest me
... but I guess you put yourself in the mind of someone who might want the file and imagine what they might search for and name your file accordingly. If you go to the Library you can check how many hits your shared files have had that is the number of people who have had the file appear in their search window, so you will know it is being seen ... at least.
Sorry I can't be more help.
WARNING Do NOT "delete" any files in the Limewire library if you ever want to see them again ... because you wont!
