How to resize casper-rw Images in Windows

How to Resize casper-rw images. TopoResize is a Free Image Resizing Tool originally written by Chris Semler. Initially created to resize images containing an ext2 or ext3 file system within Windows, such as those found in Colinux. You can use this nifty tool to create a new filesystem image as well as shrink or enlarge your existing persistent overlay images. In our case, we can also use it to resize casper-rw image loop files or even resize Pendrivelinux 2009 filesystem images. This tool works by using Cygwin to port Linux file system tools like efs2progs to Windows.

Note: The maximum possible size for a file on a FAT32 volume is 4 GB minus 1 byte. So keep in mind that you cannot exceed this limitation if your storing the resulting image on a Fat32 volume.
