It provides Windows NT4.0/2000/XP with full access to Linux Ext2 volumes (read access and write access). This may be useful if you have installed both Windows and Linux as a dual boot environment on your computer.
The "Ext2 Installable File System for Windows" software is freeware.
I've used it for ages, never had any problemsDoes the Ext2 driver access Ext3 volumes, too?
The Ext3 file system is the Ext2 file system which has been extended by journaling. Ext3 is backward-compatible to Ext2 - an Ext3 volume can be mounted and used as an Ext2 volume. Just as older Linux Kernels which do not know the Ext3 file system can mount Ext3 volumes (as Ext2 volumes), the Ext2 file system driver ext2fs.sys for Windows incorporated in this software package can do it without any problems, too. Of course you do not take advantage of the journaling of the Ext3 file system if you mount it as an Ext2 file system.
Journaling keeps the file system of a volume consistent, even though the volume has not been cleanly dismounted in the past (for instance because the computer has crashed): There is no need for running e2fsck (the "chkdsk" of the Ext2/Ext3 file system on Linux).
I have installed the Ext2 IFS software and was able to create a drive letter for a desired volume of Linux. But when I try to access that volume I get an error message "The disk in drive X: is not formatted. Do you want to format it now?" (Of course I don't want to!) Or the content of the volume appears, but when I attempt to write something I get an error message "Access denied".
The ext2fs.sys driver did not mount that volume for some reason, or it mounted it read-only.
Please run the mountdiag diagnosis tool, which you can download here: mountdiag.exe (updated, 07-19-2008).
Please run it at the command prompt and give it the letter of the drive you want to examine, for example:
mountdiag G:
The tool will give you a hint on how to resolve the problem. (Note: The mountdiag tool reads data only; it does not attempt to modify anything.)
