About Ext4/3/2

Ext2, Ext3, and Ext4 are all extended file systems commonly used for the Linux operating system. You can learn more about them from the following content.


Ext2, standing for the second extended file system, is the first commercial file system for Linux that was originally introduced in 1993. It’s designed to overcome limitations on the previous Ext file system. The Ext2 file system ranges from 2TB to 32TB and the maximum size of a single file it supports can be up to 2TB.

Since Ext2 lacks a journaling feature, it’s recommended for flash drives, such as SD cards and USB flash drives.


Ext3, or the third extended file system, is a journaled file system that was introduced in 2001 as an improved version of Ext2. Like Ext2, it can also handle a single file with a maximum size of 2TB.

The prominent advantage of Ext3 is journaling, which can help track the changes to the file system. With this feature, Ext3 is more reliable and easier to recover data after an unclean shutdown.


Ext4 refers to the fourth extended file system released in 2008. It’s the successor to Ext3 and is now the latest version of the EXT file system. It’s also a journaling file system for Linux and offers backward compatibility with Ext2 and Ext3.

Different from the older EXT file systems, Ext4 supports larger file size and partition size, up to 16TB and 1EB respectively.
