ext3 (third extended filesystem)

Ext3, or third extended filesystem, is a type of file system used by Linux computers to organize and store data on hard drives. It builds on earlier versions by adding journaling, which temporarily records changes before they are finalized. This helps protect data from corruption if the system crashes or loses power, making the system more reliable and faster to recover. Ext3 supports large storage devices and can handle many files efficiently. It's widely used because of its robustness, ease of use, and compatibility with various Linux distributions.
