Hello, Christine. LimeWire creates an Incomplete folder in the same folder as your selected download folder. If you've moved or renamed the download folder, it might have got confused. Or it might have got confused for no reason at all. Try reselecting your downloads folder (Tools menu, Options). If you're using the latest version, you can't quit with Apple + Q, but in earlier versions you could, and if you did, any recent settings you had made were lost. So always quit with the Close command, even if you have the option.

About searching with Sherlock; you don't have to index volumes to search for files, only to search for the contents of files.

I hope you get it sorted out.
