EXT2, or second extended file system, is a file system for the Linux kernel. It was the first commercial-grade filesystem for Linux.

EXT3, or third extended filesystem, is a journaled file system that is also used by the Linux kernel. It used to be the default file system for many popular Linux distributions. Its main advantage over ext2 is journaling, which improves reliability and eliminates the need to check the file system after an unclean shutdown. Its successor is ext4.
