Which of the following is the latest Linux file system?
Ext4 is the latest Linux file system. One of the improvements over ext3 is support for unlimited subdirectories. Ext4 modifies important data structures of the filesystem, such as the ones destined to store the file data. The result is a filesystem with an improved design, better performance, reliability, and features. Other improvements are:
– Supports volumes with sizes up to 1 exibyte (EiB) and files with sizes up to 16 terabytes (TiB)
– Supports extens
– Is backwards compatible with ext3 and ext2
– Uses extents to replace the traditional block mapping scheme used by ext2 and ext3
Ext2 was the first commercial-grade file system for Linux. It is no longer in use. The ext2 filesystem does not support journaling, which would help in recovery after a crash. Ext3 is the second version of the file system. The journaling feature in filesystems helps in recovery after a crash. The ext3 filesystem provides journaling capability.
There is no Ext5.
