UBIFS (UBI File System, more fully Unsorted Block Image File System) is a flash file system for unmanaged flash memory devices. [1] UBIFS works on top of an UBI (unsorted block image) layer, [2] which is itself on top of a memory technology device (MTD) layer. [3] The file system is developed by Nokia engineers with help of the University of ...
Unionfs is a filesystem service for Linux, FreeBSD and NetBSD which implements a union mount for other file systems.It allows files and directories of separate file systems, known as branches, to be transparently overlaid, forming a single coherent file system.
ext4 (fourth extended filesystem) is a journaling file system for Linux, developed as the successor to ext3.. ext4 was initially a series of backward-compatible extensions to ext3, many of them originally developed by Cluster File Systems for the Lustre file system between 2003 and 2006, meant to extend storage limits and add other performance improvements. [4]
list file attributes on a Linux second extended file system mke2fs used for creating ext2, ext3 and ext4 file systems resize2fs which can expand and shrink ext2, ext3 and ext4 file systems. On-line support was added in 2006. [2] tune2fs used to modify file system parameters. Many of these utilities are based on the libext2fs library.
dd — convert and copy a file; e2fsprogs — a set of utilities for maintaining the ext2, ext3 and ext4 file systems; fdisk — examine and write partition table; fsck — file system check; mkisofs — make an iso file system; mount — mount a file system; parted — partition manager
For Windows users, FSArchiver includes experimental support for NTFS. [1] FSArchiver supports most modern Linux file systems such as ext4, reiser4 and btrfs.. Other notable features include modern and multi-threaded compression [2] of disk image files, combined with file-based images (as opposed to block-based images most similar tools use) to enhance compression by ignoring unused clusters.
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.
The extended file system, or ext, was implemented in April 1992 as the first file system created specifically for the Linux kernel. Although ext is not a specific file system name, it has been succeeded by ext2 , ext3 , and ext4 .
