I would think if you filtered out "incomplete", that iit would help a great deal, and a lot more over time if more people do it. This is because it would (hopefully) filter out the incomplete folder that the person is apparently sharing (dumb). Obviously, NOT sharing the incomplete folder is the best method here, but how to get people who don't know better to cooperate? This issue should, in time be self correcting as more people become familiar with file sharing and as clients add features to show the length of media files and such. Then nobody would really want to download a file if they know in advance it is incomplete, even when it says it is in the name. Unfortunately, the size of the file does not always give a true representation, as encoding methods effect the size. The length of the media in minutes and seconds is in my opinion the best method available, and it should be easy to implement.
