Ext3 for large filesystems

This is from memory so I may be wrong ...

In the beginning Linux used the minix file system. This had many
limitations including as I recall 14 character filename limits.

The EXTended filestem was developed to address these problems. This was
relatively rapidly replased by the second extended filestem (ext2) (I do
not recall what the problems with ext1 were).

Ext3 extended Ext2 with new capabilities - most notably a journel. This
considerably improves the resilience of the filesystem to unexpected power
failures !
