Linux File Systems
The ext2 file system supports standard UNIX file types: regular files, device special files, symbolic links and directories. The UNIX files are supported by ext2 file system.
Ext2 file system is able to manage file systems created on really big partitions. While the original kernel code restricted the maximal file system size to 2 GB, but with recent work, it is now possible to use big disks without the need of creating many partitions.
The ext3 is a journalled file system that is coming into increasing use among users of the Linux operating system. It is the default file system for the Red Hat, Fedora and Debian Linux distributions.
The ReiserFS is a general-purpose computer file system designed and implemented by a team at Namesys. The design objectives were to increase performance over the ext2 file system, offer a space efficient file system, and to improve handling of large directories compared to existing file systems. Reiserfs uses balanced trees to store files and directories and it also offers journaling.
