Other extended file systems
There are other members in the extended file system family:
* ext2, the second extended file system.
* ext3, the third extended file system.
*ext4
ext4 (fourth extended filesystem) is a journaling file system for Linux, developed as the successor to ext3.
ext4 was initially a series of backward-compatible extensions to ext3, many of them originally developed by Cluster File Systems fo ...
