Notable examples include Rock Ridge (Unix-style permissions and longer names), Joliet (Unicode, allowing non-Latin scripts to be used), El Torito (enables CDs to be bootable) and the Apple ISO 9660 Extensions (file characteristics specific to the classic Mac OS and macOS, such as resource forks, file backup date and more).
XFS is a 64-bit file system [24] and supports a maximum file system size of 8 exbibytes minus one byte (2 63 − 1 bytes), but limitations imposed by the host operating system can decrease this limit. 32-bit Linux systems limit the size of both the file and file system to 16 tebibytes.
Since 2008, Namesys employees have received 100% of their sponsored funding from DARPA. [22] [23] [24] In 2010, Phoronix wrote that Edward Shishkin was exploring options to get Reiser4 merged into Linux kernel mainline. [25] As of 2019, the file system is still being updated for new kernel releases, but has not been submitted for merging. [3]
The table below shows the default file system, but many Linux distributions support some or all of ext2, ext3, ext4, Btrfs, ReiserFS, Reiser4, JFS, XFS, GFS2, OCFS2, and NILFS. It is possible to install Linux onto most of these file systems. The ext file systems, namely ext2, ext3, and ext4 are based on the original Linux file system.
In 2009 Squashfs was merged into Linux mainline as part of Linux 2.6.29. [ 8 ] [ 9 ] In that process, the backward-compatibility code for older formats was removed. Since then the Squashfs kernel-space code has been maintained in the Linux mainline tree, while the user-space tools remain on the project's GitHub page.
It was created by Chris Mason in 2007 [15] for use in Linux, and since November 2013, the file system's on-disk format has been declared stable in the Linux kernel. [16] Btrfs is intended to address the lack of pooling, snapshots, checksums, and integral multi-device spanning in Linux file systems. [9]

Disk partitioning or disk slicing [1] is the creation of one or more regions on secondary storage, so that each region can be managed separately. [2] These regions are called partitions. It is typically the first step of preparing a newly installed disk after a partitioning scheme is chosen for the new disk before any file system is created ...
