	Ext2 IFS For Windows
		The level of sophistication of the Ext2 file system driver's implementation is indeed comparable to Windows NT's native file system drivers.
		The "Ext2 Installable File System" software package is distributed as a single executable solution, complete with all of the features.
		It is a setup wizard which installs and configures the Ext2 file system driver.

	Linux EXT2 File System Data Recovery
		Ext2 file system is a powerful and extensible file system for Linux and it is the most successful file system in the Linux community.
		EXT2 directories are simply special files which contain pointers to the inodes of their directory entries.
		When creating an Ext2 filesystem, the system administrator may choose how many inodes to allow for a partition of a given size, depending on the expected number of files to be stored on it.

		Ext2 non è dotato di nessun tipo di journaling.
		Attualmente Ext2 è stato sostituito da una versione più recente Ext3 che introduce delle importanti caratteristiche mantenendo la compatibilità completa.

	Ext2 - Wikipedia, the free encyclopedia
		Although ext2 is not a journaling file system, its successor, ext3, provides journaling and is almost completely compatible with ext2.
		The canonical implementation of ext2 is the ext2fs filesystem driver in the Linux kernel.
		ext2 was also designed with extensibility in mind, with space left in many of its on-disk data structures for use by future versions.

	Ext2 - Biocrawler (Site not responding. Last check: )
		The ext2 or second extended file system was the standard filesystem used on the Linux operating system for a number of years and remains in wide use.
		ext2 was the default filesystem in the Red Hat, Fedora and Debian Linux distributions until supplanted more recently by ext3.
		The ext2 file system was based on the extended file system with many reorganizations and many improvements and was designed with evolution in mind, containing space for future developments.

	Ext3 - Wikipedia, the free encyclopedia
		The ext2 and ext3 file systems share the same standard set of utilities, e2fsprogs, which includes a fsck tool.
		Since ext3 aims at being mostly compatible with ext2, many of the on-disk structures are similar to those of ext2.
		The filesystem metadata is all in fixed, well-known locations, and there is some redundancy inherent in the data structures that allow ext2 and ext3 to be recoverable in the face of significant data corruption, where tree-based filesystems may not be recoverable.

	File Systems - Ext2
		The second extended filesystem, ext2 is an improvement of the first extended filesystem, which has its origins in the Minix FS.
		However, block groups are not tied to the physical layout of the blocks on the disk, since modern drives tend to be optimized for sequential access and hide their physical geometry to the operating system via the device drivers and/or and array controller.
		Secondly, the ext2 FS contains allocation optimizations: block groups are used to cluster together related i-nodes and data: the kernel code always tries to allocate data blocks for a file in the same group as its i-node.

	LWN: Speeding up ext2
		The current ext2 code takes out the superblock lock before performing block allocation; this means that only one thread can be trying to allocate space in a given filesystem at a time.
		ext2 is generally thought of as the relatively simple Linux filesystem; ext3 is the place for fancy new stuff.
		Ext2 is growing into the role of experimental filesystem; Ext3 is now the stable filesystem.

	Ext2 Linux File System
		The canonical implementation of ext2 is the ext2fs filesystem driver in the Linux kernel.
		ext2 was also designed with extensibility in mind, with space left in many of its on-disk data structures for use by future versions.
		The ext2 file system has a maximum data size of 4 terabytes, maximum filename length of 255 characters, and has variable length block size.

	FREENIX Track: USENIX 2002 Annual Technical Conference - Paper
		As part of the changes to version 1 of the ext2 superblock, the size of the inode in the filesystem was added as a parameter in the superblock.
		Ext2 had support for a limited amount of preallocation (usually only a handful of blocks, and the preallocated blocks were released when the file was closed).
		One of the reasons why we have separate code bases for ext2 and ext3 is that journaling adds a lot of complexity to a number of code paths, especially in the block allocation code.

	[No title]
		The EXT2 file system, like a lot of the file systems, is built on the premise that the data held in files is kept in data blocks.
		EXT2 directories are simply special files (themselves described by inodes) which contain pointers to the inodes of their directory entries.
		The EXT2 inodes for each Block Group are kept in the inode table together with a bitmap that allows the system to keep track of allocated and unallocated inodes.

		ext2ed, which is a text/windows (curses) interface for examining and editing an ext2 filesystem.
		It has been integrated into e2fsprogs version 1.28, but its limitations mean that it should only be used by developers who need to generate test cases.

	A Non-Technical Look inside the EXT2 File System
		The EXT2 file system attempts to allocate each new directory in the group containing its parent directory, on the theory that accesses to parent and children directories will be closely related.
		The EXT2 file system also attempts to place files in the same group as their directory entries, because directory accesses often lead to file accesses.
		The EXT2 file system is rather more complex than most people realize, but this complexity results in both the full set of Unix operations working correctly, and good performance.

	Second Extended File System - Computing Knowledgebase
		After Ext, another two filesystems were developed: the Xia File System, and the Ext2 filesystem.
		Ext2 was the direct successor to Ext, and quickly became the standard Linux Filesystem, where it stayed for years.
		However, it's successor, Ext3, does contain a Journal, and is 100% Compatible with Ext2.

	Handhelds.org - Working with File Systems for Handhelds
		These instructions tell how to use the loopback device to access an ext2 image, in which case ramdisk is not really involved at all.
		Those blocks are not in use by the ext2 filesystem, but they still have the original file contents, and hence aren't that easy compressable as empty blocks (i.e.
		Accessing cramfs is similar to ext2 ramdisk, except that cramfs is a readonly filesystem.

	What is EXT2 file system? Recover EXT2 partition - Data Recovery Service
		The ext2 file system supports standard Unix file types: regular files, directories, device special files and symbolic links.
		ext2 file system is able to manage file systems created on really big partitions.

	LUG@GT :: Articles :: Filesystems
		Ext2 is the most used filesystem for Linux because it has been around for a long while.
		Ext2 and Ext3 are irreversible; one can easily upgrade an Ext2 filesystem to Ext3, and vice versa (but why would ya?).
		Filesystems like Ext2 write these files to the data like all other data, but since Ext2 allocates storage space in blocks of 1k or 4k, the rest of that reserved section is wasted.

	SDB:EXT2 Fragmentation - openSUSE
		The ext2 file system writes files with a kind of writeahead, too, i.e.
		When you write a block in an ext2 file system, the file system occupies immediately up to 7 further successive blocks for that file.
		Finally, you also have to consider the buffer cache of the operating system, i.e., on the second read attempt, everything comes out from the RAM anyway and the data arrangement on the disk does not matter.

	Filesystem analysis
		The ext2 filesystem is the one that linux systems use most prevalently.
		Note that "every file in the EXT2 file system is described by a single inode and each inode has a single unique number identifying it.
		EXT2 directories are simply special files (themselves described by inodes) which contain pointers to the inodes of their directory entries." In order to make sense of inodes and directory entries you need to know their internal structure too.

	Converting Ext2 Filesystems to Ext3
		The Ext3 filesystem is an Ext2 filesystem with a journal file and some filesystem driver additions making the filesystem journalized.
		Converting the root directory from Ext2 to Ext3 isn't difficult, but converting it back from Ext3 to Ext2 is a treacherous process fraught with problems.
		Converting from Ext2 to Ext3 is usually easy, although converting the root partition is usually undesirable.

	FOCUS on Linux: Filesystem Security - ext2 extended attributes
		Although the definitions for most of the useful ext2 filesystem flags appeared in the kernel source at least as early as the 1.1 development series, this humble feature often takes a back seat to more exotic and recently-introduced tools for preserving and assuring system integrity such as LIDS, Tripwire, and others.
		The Linux ext2 filesystem has supported extra flags or 'attributes' for files and directories in all Linux kernels since the 1.1 development series.
		Ext2 attributes, on the other hand, are checked and honored by various system calls such as sys_open() and sys_truncate() without regard to uid or any other influence.

	Accessing ext2 - wikiPodLinux
		ext2 or ext3 is the file system format for the Linux partition used by iPodLinux on WinPods (but not on MacPods).
		There is one known ext2 file system driver available for Mac OS X. It's called ExtFSManager and can be found here (http://sourceforge.net/project/showfiles.php?group_id=64713).
		Total Commander (http://ghisler.com/) has ext2 support (you have to install the Ext2+Reiser plugin (http://ghisler.com/plugins.htm#filesys) separately), Linux partitions can then be accessed from the Network Neighborhood.
