and select run as Administrator.
This is not a transparent file system driver jusr a user space tool.
The LVM2 metadata can be complex because of the wide variety of configuration posibilities. All configurations has not been tested. If Lvm2 does not work in your system, please file a bug with your LVM2 metadata.
thank you for this release. this worked for me and recognized all my ext4 partitions.
ReplyDeleteJust 2 suggestions for the next release:
1) enable drag and drop copying
2) change the icon of the program or improve its quality

Thank you ver much for the input. I will try to implement them when i am free.
ReplyDeleteWow, finaly ext4 explorer for Windows. It's possible just mount ext4 partition and assign it with drive letter?
ReplyDeletesorry no. Its not a file system driver it cant do that. there is ext2ifs and ext2fsd but they did not support LVM and EXT4 last time i checked.
ReplyDeleteBut i am planning on using CIFS bridge so that files can be accessed transparently but i am not sure if i have time for that.
Hello, I have tried your program on my xp sp3 (italian), it works very well! Finally I can see my Ubuntu 10.04 disk !
ReplyDeleteI use it in a limited user accout (I launch it using "Run as..." administator); but on exit it gives me an error every time (application crash).
Later I'll post you the log.
Thank you.
Thanks for the input. I will look into the problem. can you tell me what error you get or create a bug report here http://sourceforge.net/tracker/?group_id=96464&atid=614865
ReplyDeleteHello, I have created the bug report
ReplyDeleteBut I think I've "discovered" what is causing the problem.
If I close with "File... Exit", ok crash.
If I close with the "Close" button, no crash.
I think this could help you.
Thanks your project
ReplyDeleteto put more 2 buttons "Back and next" would not be a bad idea.
I am looking into the problem.
ReplyDeleteand i am also looking into adding some new features like the back and next buttons as you mentioned.
thx a lot man:)
ReplyDeleteThanks for ext4 on windows)
ReplyDeleteUnfortunately, it doesn't seem to do anything. Just shows empty panes. I hit "rescan system" and that doesn't seem to do anything either.
ReplyDeleteI'm trying to access an LVM partition on an external drive. Running Windows 7 64-bit.
If I run System Information, Windows shows it can see the disk. Also I can "mount" it via ext2fsd but that can't read LVM.
I would feel more comfortable if it gave me a choice of drives. I have no confidence that it's actually doing anything.
Thanks,
Lyle
hello Lyle. Are you running it as administrator?
ReplyDeletecan you show me your log file. it is created in same directory where the application is.
Many thanks for this program! The ability to use it as a driver would be even better, of course :)
ReplyDeletelove it...just what i needed....works great...thankyou thanyou
ReplyDeleteI can confirm the problem Lyle reported. I run here a uptodate Windows 7 64-bit with ext2explore-2.2.70-bin.zip. When I start ext2explore (with or without administrativ rights) the program can't find my ext4 formated usb stick. The log says...
ReplyDeleteNo of disks 0

Good soft ! Good Job !
ReplyDeleteI use it on a Win 7 32 bit and explore files on a Fedora 13 (lvm2 / ext4).
Can you add a warning if it sees no disk to try to run it as an Administrator ?
thanks for the support guys. I have changed some codes and it will now dispaly a messagebox if 0 disks detected (usually not running as administrator). Also it will print error code on why it failed. can someone (for those having win7 problems) test it and tell me the error code. I have also made the file/folder names sorted.
ReplyDeletethe executable for testing is ext2explore-debug.zip
Thanks
ext2explore-debug seems to work fine for me (Windows 7 32-bit). I'm waiting for the driver, but till then the first feature I think you should implement is the ability to « open » files, by saving them in a temporary folder and then opening them with the default program in Windows. (Correct me if I'm wrong, but right now if I want to listen to music that is on my ext4 partition, I have to save the files on the windows partition and then open them.)
ReplyDeleteAnyway, big thanks for this! :)
NB: even read-only support for the future driver is fine for me :)
Thanks a lot for the EXT4 support. I'm able to access my Linux drive, still when I tried to copy a very big file Ext2explore stopped the copying somewhere at 3% without giving any error message.

I've tried using the debug version and when it failed I could open it up in Visual Studio. The error I got was:
ReplyDeleteUnhandled exception at 0x00a499ca in ext2explore.exe: 0xC0000005: Access violation reading location 0x01e60000.
The disassembly of the instruction causing the trouble (00A499CA) looks like this:
00A499C1 lea ecx,[eax*4+10h]
00A499C8 mov edi,ebx
00A499CA rep movs byte ptr es:[edi],byte ptr [esi]
00A499CC mov eax,dword ptr [edx]
00A499CE mov ecx,dword ptr [eax+8]
I wonder whether there is a good way to map this back to the original source-code ... :)
Tried to investigate this further, but Visual Studio complains that "No symbols are loaded for any stack frame. The source code cannot be displayed."
ReplyDeleteUnfortunately I don't have Qt installed to recompile everything from sources.
hey catalin, in order to debug you will need debug build which is like 150MB. but you can compile it using qt. QT open source version is freely available.
ReplyDeleteI am looking into the problem and try to fix it.
@Niavlys. Lets see what i can do. I am willing to write an IFS driver but i am very new to Windows Kernel Programming. In the other hand porting FUSE is also another option.
Congratulations great job !!!
ReplyDeleteHey guys, I would like to ask about files larger than 1.35 gigs. It seems that copying to the windows partition from an ext4 partition works but in my case in a 2gigs file only the first 1.35 gigs are copied...
ReplyDeleteIs it normal? Do I have to do something in order for it to work better?
thanks!
anilikos, i have tested the application for upto 5 gigs also checked the MD5 sums. it was ok. So it is supposed to work but there might be some bugs. Does it happen to all large files? try that with another file with similar size.
ReplyDeletethanks
How foolish of me reporting before even trying another file!
ReplyDeleteYou were right!
Thanks!!!!!!
Thank you for sharing! It isn't very polished but it does what it is supposed to do, it's free and it's based on the excellent Qt toolkit so it looks great too.
ReplyDeleteSince there isn't a filesystem driver this is the next best thing and you have my thanks for sharing.
I just tryed it on a computer that has both normal and LVM2 partitions and only the normal partitions is showed, can it be because I used a full drive for LVM? Part of the log looks like this:

thanks for pointing it out. the code doesn't work for full disk lvm. i will fix it sometime soon.
ReplyDeleteYour program is perfect.
ReplyDeleteIt works well.
Thank you.
The only strange thing is there is no way to enter to folder (directory) using keyboard.
Okie ... I tried to get the latest release (2.2.71) and ran the prog... but it just detected no disk.
ReplyDeletehere is the log...

Are you sure you are running it as administrator. error code 5 means access denied. right click on executable and select run as administrator.
ReplyDeleteHi Manesh, thanks for the utility. However, I have an external USB hard drive formatted with ext4, and nothing shows up in the panes. The ext2explorelog.log file contains this:

Manish, I just wanted to say "thank you" for your efforts in updating Ext2read for EXT4 with extents. Much appreciated.

I also had a problem accessing an external drive. It is formatted ext2 so I'm not sure what the problem is. I also get "error code 2".
ReplyDeleteInstalled on windows 7 64bit, ran as admin but it is not seeing my 2TB USB disk formatted as ext4.
ReplyDeleteerror code 2, I forgot to mention
ReplyDeleteHi there. Program works great on Windows 7 x64, except that it can't access the ONE folder in my Ubuntu 10.10 install that I want to access. It's the folder where all my torrents download to, so it's huge (about 160 gigs). I'm not sure if that's the problem. I can explore every other folder I've tried, but when I double click this particular folder, nothing happens. No files show up and no expansion arrow appears next to the folder name. :(
ReplyDeleteThank you for the great tool. However, accessing LVM2 volume formatted with ext3 doesn't work correctly:

Hi.
ReplyDeleteApplication works great on my 1.5TB drive formatted to ext3 with WinXP. I have to questions:
1.
I downloaded version 2.2.71 but when I go to "About", it still shows 2.1. Is there wrong file linked?
2. Is there any way to select more files to copy?
thanks. Andrew
Tried to use you program, I can see my 37.5GB ext4-lvm2 partition, but big files (more than 100MB) saved as 472K files only. there is an issue with saved files filenames, as well as with saving folders. If you would like a detailed report, please contact me elitevet @ gmail . com.

Hello!
ReplyDeleteThanks for this program!
I am running Windows 7, and when I try to copy a large file (I've tried different sizes - starting with 500MB all the way to 6000MB) from an Ubuntu 10.10 ext4 partition, it copies just the first part of the file (that differs between files, too; I haven't been able to link copied file sizes and real file sizes).

ReplyDeleteThe next thing to think about is just how much pressure you're looking for the gay sizegenetics therapist to use on you. Different practitioners have different styles when they perform an erotic gay sizegenetics. You will need to communicate with your therapist so construct y will know exactly the best after all in an erotic gay sizegenetics. You'll be able to ask your gay sizegenetics therapist what their style it is usually and whether or not they're now able to adapt it for ones needs and desires. Whenever you have a nice pressure level you find very enjoyable, please ensure that you mention this while you book the appointment with your sizegenetics.
