Win7下读写Ext2/Ext3/Ext4文件系统

Linux文件系统格式一般是Ext3,Ext4外加LVM，那么如何在Windows上读写这些分区呢？

推荐以下几款软件：

1. ext2Fsd （http://www.ext2fsd.com/）

可以读写Ext2/Ext3文件系统，不支持Ext4文件系统和LVM。

在Windows7下，安装文件Ext2Fsd-0.51.exe需要设置为管理员运行和兼容WindowsXP
SP3模式。

Ext2Fsd is an ext2 file system driver for
Windows  (2k,  XP, Vista and
Win7). It’s a free software. Anyone can modify or
distribute it under GPL2.

Features Ext2Fsd supports:

ext2/ext3 volume reading & writing
ext3 journal replay when mounting
various codepage: utf8, cp936, cp950 …
mountpoint automatical assignment
large inode size: 128, 256, …
large file size bigger than 4G
CIFS sharing over network
htree directory indexing
ext4 extent read-only, no  size truncating and
expanding support
Fast fsck (uninit_bg) and group block checksum support
64k block-size, support compatible to Linux
ext4 and e2fsprogs
OS: 2k, xp, vista, server 2003/2008, win7

Features Ext2Fsd doesn’t support:

fully ext3 journal support
ext4 extent support
LVM and Linux raid (md)
NT4 is no longer supported.

2. Ext2Read （http://sourceforge.net/projects/ext2read/）

支持Ext2/Ext3/Ext4和LVM，但是只读的。

Ext2Read is an explorer like utility to explore ext2/ext3/ext4
files. It now supports LVM2 and EXT4 extents. It can be used to
view and copy files and folders. It can recursively copy entire
folders. It can also be used to view and copy disk and file

Features

View and copy Ext2/Ext3/Ext4 files and
folders.
Ext4 Extents support.
LVM2 Support
Recursively copy whole directories
LRU based block cache for faster concurrent
access

3. Ext2IFS （http://www.fs-driver.org/）

可以读写Ext2，以Ext2方式挂载Ext3文件系统（不支持Ext3日志），不支持中文！

It provides Windows NT4.0/2000/XP/2003/Vista/2008 with full
access to Linux Ext2 volumes (read access
andwrite access). This may be useful if you have installed
both Windows and Linux as a dual boot environment on your
computer.

What features are supported?

Complete reading and writing access to files
and directories of volumes with theExt2 orExt3
file system.
Supports features which are specific to the I/O-system of
Windows: Byte Range Locks, Directory Notfication (so the Explorer
updates the view of a directory on changes within that directory),
Oplocks (so SMB clients are able to cache the content of
files).
Allows Windows to run with paging files on Ext2
volumes.
UTF-8 encoded file names are supported.
The driver treats files with file names that start with a dot
“.” character ashidden.
Supports GPT disks if the Windows version used also does.
Supports use of the Windows mountvol utility to create
or delete drive letters for Ext2 volumes (except on Windows NT
4.0). See also section“Can drive letters
also be configured from scripts?”.

What features are *not* supported?

Inodes that are larger than 128 bytes are not supported.
Access rights are not maintained. All users
can access all the directories and files of an Ext2 volume. If a
new file or directory is created, it inherits all the permissions,
the GID and the UID from the directory where it has been created.
There is one exception to this rule: a file (but not a directory)
the driver has created always has cleared “x” permissions, it
inherits the “r” and the “w” permissions only. See also
section“What
limitations arise from not maintaining access rights?”.
The driver does not allow accessing special files at
Ext2 volumes, the access will be always denied. (Special files are
sockets, soft links, block devices, character devices and
pipes.)
Alternate 8.3-DOS names are not supported (just
because there is no place to store them in an Ext2 file system).
This can prevent legacy DOS applications, executed by the NTVDM of
Windows, from accessing some files or directories.
Currently the driver does not implement defragging
support. So defragmentation applications will neither show
fragmentation information nor defragment any Ext2 volume.
This software does not achieve booting a Windows operating
system from an Ext2 volume.
LVM volumes are not supported, so it is not possible to access
them.

4. DiskInternals Linux Reader for
Windows (http://www.diskinternals.com/linux-reader)

支持Ext2/Ext3/Ext4, HFS 和 ReiserFS，只读。

There are a number of evident merits of the program, which you
should know. First of all,DiskInternals Linux Reader is
absolutely free. Secondly, the program provides for
read-only access and does not allow you to make records in file
system partitions. This guarantees that the interference in an
alterative file system will not affect the work of Linux later.
Apart from this, it is necessary to note, that it gives you an
opportunity to use common Windows Explorer for extracting data. A
preview option for pictures is one more pleasant point, which is
worth mentioning.

How to get safe and quick access to any file systems?
DiskInternals Linux Reader is an easy and short way to solve the
problem!

While saving, it ignores file security policies. It means that
it is possible to access absolutely any file on a Linux disk from
Windows. The program can create and open disk images.

Linux Reader is 100% FREE.
