Ext2 IFS for Windows
Tired of having to use FAT32 to share files between your Linux and Windows installation?
Prefer to use Ext2 or Ext3 but disappointed that Windows doesn't support it natively?
Well, then Ext2 IFS is the thing for you!
With Ext2 IFS you can mount an Ext2 partition (and Ext3, since Ext3 is nothing more than Ext2 with journaling) under Windows!
"It provides Windows NT4.0/2000/XP/2003/Vista with full access to Linux Ext2 volumes (read access and write access). "
"It installs a pure kernel mode file system driver Ext2fs.sys, which actually extends the Windows NT/2000/XP/2003/Vista operating system to include the Ext2 file system. Since it is executed on the same software layer at the Windows NT operating system core like all of the native file system drivers of Windows (for instance NTFS, FASTFAT, or CDFS for Joliet/ISO CD-ROMs), all applications can access directly to Ext2 volumes. Ext2 volumes get drive letters (for instance O:). Files, and directories of an Ext2 volume appear in file dialogs of all applications. There is no need to copy files from or to Ext2 volumes in order to work with them."
