EXT4

The standard, mature filesystem used by most Linux installations to organize files on disk.

EXT4 is a widely used Linux filesystem that tracks how files, directories, and their metadata are laid out on storage, with journaling to survive crashes. Implementing it means understanding that on-disk layout precisely. microZeus creates EXT4 filesystems from scratch.
