Accessing Linux Filesystems in Windows

 in
You don't have to wait for Microsoft to support Linux filesystems to get at your Linux files from Windows.
rfstool

ReiserFS increasingly has become a popular Linux filesystem, because of its fault-tolerance capabilities. rfstool allows access to ReiserFS partitions from Windows to Linux; however, it supports only read-only access, and the developers, according to their Web site, have no plans to change that. The tool is available from freshmeat.net/projects/rfstool.

LTOOLS

The previous tools lead us to the tool to which this article is dedicated. Unlike Ext2fsd and rfstool, which are specific to one particular class of filesystems, LTOOLS are more generic. They support ext2, ext3 and ReiserFS. LTOOLS are a set of command-line tools, along with two GUIs and a Web-based front end, to enable the reading of and writing to Linux ext2/3 and ReiserFS filesystems from nearly all DOS or Windows (XP, 2000, NT, ME, 9.x or 3.x) versions, running on the same machine or remotely. So, whenever you're running DOS or Windows, and you desperately need to read or write to a Linux partition, which may be on your own computer or any other, you can make use of LTOOLS. LTOOLS also is a great tool for fixing your Linux installation, if you do not have a live CD.

As mentioned previously, LTOOLS comes with two different GUI interfaces to enable you to access your Linux partitions. LTOOLS comes with LTOOLSgui, which is a Java-based graphical user interface for local or remote access to your Linux files, and LTOOLSnet, which is a Microsoft .NET-based user interface, which also provides local or remote access.

If you do not like using non-free Java or MS .NET, you can use your Web browser as a graphical front end for LTOOLS. To achieve this functionality, the package contains LREADsrv, which is a simple Web server, making your Linux filesystem available in an Explorer-like view in your Web browser. Using LREADsrv, you can allow remote access to your Linux partitions, as well as to your DOS/Windows partitions.

Installation of LTOOLS

LTOOLS comes with a default Windows installer, which seems quite dated. After following the normal installation procedure, the installer creates an entry in your start menu called LTOOLS from which you can access a plethora of interfaces that allows you to access your Linux filesystems.

LTOOLS comes with support for nearly all Windows versions; however, all of the interfaces won't run on all Windows versions. LTOOLS provides two different console versions for Win9x/ME and Windows NT/XP.

Overview of LTOOLS—Command-Line Interface

The command-line interface provides basic functionality for writing and retrieving data from Linux. LTOOLS commands have the following format. All commands have three files associated with them, for example:

ldir.bat

This command lists directories; however, it is not a program but a script. This script, depending on your system, further invokes either of these two programs: LdirDOS.exe or ldirNT.exe. The first one is for Win9x/ME, and the second one is for Windows NT/XP.

Many LTOOLS commands have a logical syntax. For example, partition names are Linux names. So, if I want to copy a file called vars.inc from /root (which is on /dev/hda2) to my C: drive, I would do the following:

lread.bat --s/dev/hda2 /root/vars.inc C:\vars.inc

Similarly, for writing to Linux, I would do this:

lwrite.bat --s/dev/hda2 C:\vars.inc /root/vars.inc

Along the same lines, LTOOLS also has the commands shown in Table 1.

Table 1. LTOOLS Commands

lread.bat Read and copy files from Linux to DOS; sample usage: lread.bat --s/dev/hda2 /root/vars.inc C:\vars.inc
lwrite.bat Copy files from DOS to Linux; sample usage: lwrite.bat --s/dev/hda2 C:\vars.inc /root/vars.inc
ldel.bat Delete Linux files or (empty) directories—same as rm --f and rmdir in Linux; sample usage: ldel.bat /root/vars.inc
lchange.bat Change Linux file attributes and owners—analogous to chmod; sample usage: lchange.bat --s/dev/hda2 754 /root/vars.inc
lren.bat Rename Linux files—analogous to mv; sample usage: lren.bat --s/devhda2 /root/vars.inc /root/var2.inc
lmkdir.bat Create a new Linux directory—analogous to mkdir; sample usage: lmkdir.bat --s/dev/hda2 /root/newdir
lln.bat Create a symbolic link—analogous to ln; sample usage: lln.bat --s/dev/hda8 /root/link /root/vars.inc
lcd.bat Change directory—analogous to cd; sample usage: lcd.bat /home/
ldrive.bat Set the default Linux disk drive; sample usage: ldrive /dev/hda8

ReiserFS is not supported via the above-mentioned tools. Thus, LTOOLS also ships with rfstool, which can be used to read from ReiserFS partitions. In order to read the hard disk under Windows NT/2000/XP or UNIX/Linux, you need administrator rights. If you are running LTOOLS under a non-administrator account, you may not be able to access the hard disk. LTOOLS does not respect Linux ownership. This means that if users were to mount the root device, they could change anything, including /etc/passwd/.

is there any software

sushant's picture

is there any software available that will help me convert ext4 partition to NTFS or FAT32??

Very informative article

Hi,

This article is very informative and useful for "dual boot" machine users.

Thanks,

Ext4 support

Now the ext2fsd driver has been updated to support ext4: http://www.acc.umu.se/~bosse/ext2fsd-0.48-bb4.zip

Ext4 and extents support

Hi,
You can use the new release of my Ext2read to view copy ext4 file systems with extents enabled. You can download it from http://ext2read.sf.net

release thread is here:

ext2fsd doesn't work for ext4

No it doesn't work. You can

No it doesn't work. You can just see / directory and that's all.

Ext2fsd Problem with Ext4

SouthFloridaNetworks's picture

"""Ext2fsd ... allows access from Windows to ext2 filesystems ... Ext2fsd does not only read ext2 partitions, but also Ext2 was one of the first de facto Linux filesystems, and many new Linux filesystems, such as ext3 and ext4 are backward-compatible with it. Thus, the driver can work with ext3 and possibly ext4."""

While technically true, there is one small problem. Ext2fsd will only work with a 128 inode, which is the default in the EXT2 File system. The default inode for Ext4 is 256, rendering it incompatible with Ext2fsd. Also, most newer operating systems, such as Ubuntu 9.04, will by default install a 256 inode with their EXT3 filesystem, in anticipation of upgrading to Ext4 in the future. While you can manually specify to format your new file system utilizing a 128 inode with EXT3, to keep compatibility with Ext2fsd, I'm not sure if the same is true for the Ext4 filesystem, considering that most of the newer attributes of the Ext4 filesystem are stored in the extended Inode. In other words, by installing the Ext4 filesystem with a 128 inode, it's basically the same as having an Ext3 filesystem. (though I could be wrong on this final point).

same problem

Lars (anonymous)'s picture

I ran into this with a new Ubuntu installation... I installed two Linux partitions, one ext4 (root partition) and one ext3 (home partition). The latter I chose ext3 for better compatibility with existing tools for accessing Linux fs's from Windows.
Unfortunately, I found out afterwards that Ext2IFS, and apparently Ext2FSD, only work with a 128 inode fs, which is not what I have.

Thanks for the pointer to LTOOLS. I'll give that a try.

Thanks

Thanks for the info. Good comment. Now to wait for a Windows EXT4 driver to come out...

There is a column talked

There is a column talked about the detail LTOOLS in issue 79. The link is http://www.linuxjournal.com/article/4138.

Where is this app?

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
