The Extended File System (Ext) is a family of file systems consisting of: ext, ext2, ext3, ext4
Contents |
Ext2
ext2 or the second extended file system is a Linux filesystem designed as a replacement for ext. Note that ext3 is mostly compatible with ext2.
Ext3
ext3 or the third extended file system is a Linux filesystem. Its main advantage over ext2 is journalling which improves reliability and eliminates the need to check the file system after an unclean shutdown.

Ext3
Tools
The Sleuthkit and R-Studio can be used to perform recovery of data from the EXT2 filesystem. Various data carving tools like Foremost and Scalpel also support the ext2 filesystem.
