filesystem

The `lost+found` directory in Linux is crucial for maintaining file system integrity, housing orphaned files during system recovery. Created by `fsck`, it stores files with inconsistencies found during checks. Regularly running `fsck`, especially after crashes, helps prevent data loss. Files in `lost+found` should be inspected before deletion to ensure they are not needed, maintaining strict access permissions to safeguard their contents. This directory should not be used for regular data storage.
