Journaling file system

A journaling file system is a type of file management system used in computers to keep track of changes to files and directories. It works like a diary that records actions before they are made permanent, which helps prevent data loss and corruption, especially during crashes or power failures. If an error occurs, the system can refer to the "journal" to restore the state of the files to a consistent condition. This makes the system more reliable and efficient in maintaining data integrity compared to traditional file systems that do not keep such records.
