What is ext4?

Ext4, or fourth extended filesystem, is a journaling file system for Linux, developed as the successor to ext3. It's commonly used as the default file system for many Linux distributions due to its improvements in performance, reliability, and capacity over its predecessors. Ext4 supports larger file sizes and volumes, reduces fragmentation, and improves disk space allocation.
