When you have a computer with multiple partitions on the same disk or several disks with different partitions, things start getting bad if one of them is a Linux Ext or Ext2 partition: Usually, you can’t access the Linux partition from your Windows computer, Microsoft totally ignore your disk/partition.
In order to correct this, you can/must use a special Windows driver able to recognize correctly those Linux Ext/Ext2 partitions. Ext2 IFS provides full read/write access. It’s is essentially a kernel ext2/ext3 filesystem driver for Windows. When installed in your Windows computer, it simply becomes able to natively access the Linux disk. After installing, you can mount your Linux partition under a drive letter, just like you would an NTFS partition. The drive will be available in Explorer and within any file browser dialog in your favorite Windows applications.
