ext3

Ext3, or Third Extended File System, is a type of file system used by Linux operating systems for organizing and storing data on hard drives. It builds upon its predecessor, Ext2, by adding support for journaling, which helps protect data integrity by keeping a log of changes. This means if the system crashes or loses power, Ext3 can recover more easily from errors. Ext3 is known for its reliability and performance, making it a popular choice for servers and workstations where data safety is critical. It has largely been succeeded by newer systems but is still notable in computing history.
