Best Windows ext2 driver


I need to be able to share a drive between Windows and linux, and the best bet seems to be ext2. I need a fs that can support 4+GB files, and fat is not an option.

I have searched online and the forums and found two drivers ext2fsd, and ext2ifs. Now my question for anyone that uses them is how well do they work, and which is the best?

The best and easiest file syatem is FAT32 - both Windows and Linux can read and write them. If your Win partition isn't already FAT32, I'd create a new partition specifically for sharing files between the 2 OSes.

Like I said in the original post, Fat is not an option. Unless something has changed recently FAT does not support 4GB+ files, which I need.

I think the MAX file size for fat is 1-2GB

http://support.microsoft.com/default...b;en-us;310525 appears to say that (under XP)

FAT32 supports drives up to 2 terabytes in size.

Max file size in fat32 is 4gig

max volume size is realistically 32 gig (theoretically higher)

I personally wouldn't let windows read and write a ext2 partition, but if it was a separate shared partition and not a main partition of the linux system then it should be okay.

As for best, I don't know as I only need to use fat32 shared... And I run win very little these days except in virtual machines.

FAT32 supports drives up to 2 terabytes in size.

I need support for files larger then 4GB+

This link states that the max file size for fat32 is 4GB, and fat16 is 2GB

Yep, I figured it probably would be... Just another note... Not sure of the max file size in ext2 to be honest. It used to be 2 gig but I think that was altered.... But it might be something to watch for in the various filesystem drivers...

Don't know if windows has any jfs or xfs support? and linux ntfs support is sketchy... Hmm. tough one.

Just a quick look suggests the max file size in ext2 is 16 gig with a 1k block size and 2 TB with 4k block size...

Ya, I have looked into reiserfs. But the only program is an application you run, but it does not allow your partition to show up as a regular drive, which I need.


As for ext2/3 I'm almost 100% sure that limit was removed.

After some reading (I was bored anyway) I have to wonder if the windows implimentations of ext2 are going to support file sizes greater than 2 gig. Something to do some searches and reading on I think...

From my understanding you need a 2.6 kernel for large file support and the partition needs to be created with a larger (eg 4kb) block size... So on my box even with 2.6 I have a limitted file size, apparently.

Maybe someone else knows more on this. I haven't had to worry about large files...

I never thought of the windows drivers having the limitations. I tried looking up the info on thier web sites, but I can't find anything usefull.

Hopefully some will be able to answer this question for me.

I really hope I don't get stuck with captive-ntfs since its write speed it horrible.
