Alt.binaries Problems In Finding Files

[Harry]

Someone posted a song for me in an alt.binaries group but I have not been able to find it even though I have looked in the exact group and done a search within the group using Free Agent. I'm wondering if for some reason some news servers are not able to read the names of all songs in alt.binaries groups. I also notice that many off the songs in the group have files missing since a song is usually split up into a number of files. What's the problem with these binaries groups?
