Ddirectory.rst3 Directory Entries
6 In an ext4 filesystem, a directory is more or less a flat file that maps
8 filesystem. There can be many directory entries across the filesystem
11 such, directory entries are found by reading the data block(s)
12 associated with a directory file for the particular directory entry that
18 By default, each directory lists its entries in an “almost-linear”
20 sense because directory entries are not split across filesystem blocks.
21 Therefore, it is more accurate to say that a directory is a series of
22 data blocks and that each block contains a linear array of directory
26 directory is of course signified by reaching the end of the file. Unused
