Linux file system

Linux uses a unified, hierarchical file system to organize and store data on disk partitions. It places all partitions under the root directory by mounting them at specific points. The file system is case sensitive. The Linux kernel manages hardware resources and the file system, while users interact through commands interpreted by the shell. Journaling file systems like ext3 and ReiserFS were developed to improve robustness over ext2 by logging file system changes to reduce the need for integrity checks after crashes. Ext4 further improved on this with features like larger maximum file sizes and delayed allocation.Read less
