In windows 7 when you make a file that is 1 to 600 bytes it shows space on disk as about double what the size is. In windows 8 and 8.1 anything smaller than 600 bytes shows 0 space taken on disk. I just wanted to know why this is? My teacher was stumped as well he said maybe anything smaller than 600 bytes is stored in the file directory but that was just a theory.
