The extended file system or ext was implemented in April 1992 as the first file system created specifically for the Linux kernel. It has metadata structure inspired by the traditional Unix File System (UFS) and was designed by Rémy Card to overcome certain limitations of the Minix file system.
It is the first of the extended file systems. It was superseded by both ext2 and xiafs, between which there was a competition, which ext2 won because of its long-term viability.
[edit] 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, the fourth extended file system.
