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. The file system driver Ext2fs.sys caches file data and the file system's meta data such as directories and all the on-disk structures of the Ext2 file system. (It uses the file cache of the Windows NT operating system.) Therefore it is performant. The level of sophistication of the Ext2 file system driver's implementation is indeed comparable to Windows NT's native file system drivers. The "Ext2 Installable File System" software package is distributed as a single executable solution, complete with all of the features. It is a setup wizard which installs and configures the Ext2 file system driver.
