Is there a way to read ext4 partitions from Windows? If so, what can I do?

Try Linux Reader by Diskinternals, it's the best tool I have found that really works well. Unlike Ext2Fsd, Ext2Read or Ext4Explorer which don't even give you basic information like how many files you have when you open up a folder. –  sammyg May 24 '13 at 17:24
    
This is a useful question. –  Colonel Panic Jun 22 '13 at 14:57

Ext2Read works swell. It can also open & read disk images ( eg: Wubi disk images)

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

You sure @Andreja ? might be false positive or gotten infected from a dormant virus. –  Sathya Sep 13 '10 at 16:39
    
@Andreja Ran it by Sophos & Symantec Endpoint, comes out clean. –  Sathya Sep 13 '10 at 16:43
    
There are several reviews on the site of users complaining about virus infection. Ad-Aware reported it as infected to me. I'll do some more testing on my side and report this to project's mailing list. As for the report, it seems that Anubis is down at the moment. The PDF version of the report is here. It clearly shows where the virus is poking. –  AndrejaKo Sep 13 '10 at 17:47
    
Here are results of VirusTotal and Anubis (from a clean system). To me it looks like it's poking around in registry where is shouldn't be poking around. –  AndrejaKo Sep 13 '10 at 18:11

It doesn't support removable devices. Try putting a SD card with an Ext4 partition on it inside a SD card reader and try reading it with this software. It won't work. It only supports internal HDD devices. For external and removable, get Linux Reader by Diskinternals. –  sammyg May 24 '13 at 16:35

Well not really a solution, but I use VirtualBox, use it as a bridge.

In windows add a raw disk, install a linux guest OS, add a shared folder, then you can read/write ext4 in virtualBox. –  Kaizoku Dec 24 '09 at 14:10

EXT2FSD works for reading ext4 filesystems, though not all of ext4's capabilities are supported.

It doesn't, only theoretically; check out this comment: linuxjournal.com/article/9449#comment-337357 –  alex Sep 8 '09 at 4:42
    
@alex : Just only 3 weeks back I was forced to mount an ext4 disk for recovery. EXT2FSD actually read it (didn't test write, because I only wanted to recover certain data)... –  caliban Sep 8 '09 at 5:03
    
@alex : could be wrong on the drive format though on second thoughts, will double-check and update. –  caliban Sep 8 '09 at 5:07

I wanted to recommend the same app, but I was put off by the comments. If it worked for you, edit your response to let the OP know it works. Positive feedback on an app is important. –  alex Sep 8 '09 at 6:15

It apparently works if the ext4 was created without the extent option. See soluvas.com/… –  harrymc Nov 15 '09 at 8:37

There is now another solution - Paragon ExtFS for Windows, which acts as a file system driver and so you don't need to use a specialized program to access your files.

From the website:

- Fast and easy read/write access to Ext2 / Ext3 / Ext4 under Windows
- The only solution with Ext4 read - write support!
- Easy-to-install and supports Windows 8 / 7 / Vista / XP

I had never seen it before, but seems solid. I'm testing it now. –  Paulocoghi Jun 12 at 13:53

This is the best –  Anwar Dec 9 at 13:09

If you want to dual boot Ubuntu (or any Linux-based OS) with Windows and read ext3/ext4 filesystem, you can use Ext2FSD. Although you may need to take special steps as explained below.

I’ve successfully used Ext2fsd on Windows 7 to read my ext4 (!) filesystem this way.

For those interested, more detailed how-to is here: Read ext3/ext4 Partition from Windows 7

Hope this helps!
