The difference is, unlike the data in regular files, where the Filesystem ignores its contents, the data in the blocks of diretories are structured (struct ext2_dir_entry_2) and interpreted by the ext2 driver during pathname lookup. > 2.I know in ext2 the whole disk is made up of the boot > block and some block groups.
