<H2>Release 1.47.0 of e2fsprogs is available!</H2>

<P>On February 5, 2023, version 1.47.0 of e2fsprogs was <A
HREF="http://e2fsprogs.sourceforge.net">announced</A>.</P>

<H2>Ext2fs Utilities</H2>

The following Ext2fs Utilities are available:

<UL>
  <LI><A HREF="http://e2fsprogs.sourceforge.net">e2fsprogs</A>, which consists of
		e2fsck, mke2fs, debugfs, dumpe2fs, tune2fs, and most
		of the other core ext2fs filesystem utilities.
  <LI><A HREF="http://dump.sourceforge.net/">dump</A>, which will
	allow you to make backups of your ext2
	filesystems.  It uses a format which is compatible with the
	BSD dump and restore programs.

  <LI>defrag, which will defragment your ext2 filesystem
  <LI>ext2ed, which is a text/windows (curses) interface for examining and
		editing an ext2 filesystem.  
		It unfortunately is limited to filesystems smaller than 2GB,
		and is heavily Intel byte order dependent, and has apparently
		been abandoned by its original author.  (So for those
		people who were used to seeing ext2ed in older Linux 
		distributions, and wondered where it went to, that's 
		the explanation.)
		<P>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. </P>

   <LI><A HREF="http://www.sourceforge.net/projects/ext2fsd">Ext2fsd</A>,
	An ext2
	filesystem driver for Windows NT/2K/XP.  The most recent
	version has read-write support.
