If you currently have Windows running and you realize that you need some files for your work which you have stored on an Ext2 volume of your Linux installation, you no longer have to shut down Windows and boot Linux!
Furthermore, Windows will now be able to handle floppy disks which have been formatted with an Ext2 file system.
Linux Ext3 volumes can also be accessed.
There have been several times in the past when this would have helped me out immensely!
Thanks to Rupert for putting me on to this.
