For those are downloading Visual Studio code name "Orcas" Beta 1 files from Microsoft Downloads, you may have seen what appears to be a misprint:
I can assure you that the Team Foundation Server with Team Suite VPC is much larger than 9 KB total and that we're not using a compression technology from an advanced alien civilization.
To make a long story short, we sometimes have the need to shortcut our publishing system to publish some of these really large files in a timely manner. To do so, we need to put placeholder files for each file expected in the download. In this case, the placeholders are only 1 KB. Since the file size displayed comes from the files that go through the system, you're seeing 1 KB when in fact these are 700 MB volumes of a self-extracting file.
