My guess is that the filesystem has a block-size of 4KB. A file is stored over a set of blocks of this size. Which means that if a file is smaller then 4KB, it will still use a 4KB block. As far as I know, only reiserfs has the "notail"option which will try to stick multiple smaller files into a single block. -- Joost
