This time it has the potential to produce much smaller output files since it ONLY copies the active blocks and not all of the blocks related to undo history. This is done for "Save As" and "Backup Project". Normal save can't take advantage of this, but then it really doesn't need it as it has to depend on vacuuming. The vacuuming at close has been adjusted to utilize CopyTo() so it should produce similarly small files as long as the vacuuming happens when the project is definitely closing.
