Questions tagged [ext3]

Ext3 is a linux filesystem.

ext3 (or third extended filesystem), is a journaled file system that is commonly used by the Linux kernel. It is the default file system for many popular Linux distributions. S

The filesystem was merged with the mainline Linux kernel in November 2001 from 2.4.15 onward.

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

See Wikipedia for details on ext and ext3.
