Or, do files sit connecting for ages & then get stuck needing sources forever? If that's the case, you're probably seeing fake files.

If you're searching for music files, use the All Types search & search for artist or album rather than song title. Go for a file with 10 sources or less...stay away from the files with huge numbers of sources.
If you're searching for video files, always chech the file with Bitzi before download. If a file has heaps of sources but no Bitzi rating, chances are it's a fake.
