How to Create a casper-rw persistent or writable persistence file from Windows: Written for convenience, here is a simple Casper-RW Creator tool. This software should enable its user to quickly and easily create a casper persistent image from within Windows. By simply appending the "persistent" boot parameter, the file created by this tool can be used to save or store changes. You can then restore those changes on subsequent boots.
Also known as an overlay image, this file works as a companion to your Ubuntu Live Bootable USB. Allowing the Live system to act similar to a full installation.
The following tutorial will show you one way to create a writable Casper partition on your USB flash drive. The benefit of using a casper-rw partition as opposed to a casper-rw block file is that you can expand your persistent storage beyond 4GB. This is very useful if you have a flash drive that is 8GB or larger and you want to use all of its remaining space for persistent storage. The drawback is that Windows will not see the secondary casper-rw partition (in Windows, your drive will appear to be smaller than it is).
The following tutorial explains how to create a larger casper-rw loop file (or writable file) for your Ubuntu based flash drive install. For example on: Ubuntu, Xubuntu, Kubuntu, Crunchbang or Linux Mint. A larger casper-rw loop file is particularly useful for those who have performed a Linux install to a large thumb drive using a Windows USB tutorial and need more persistent storage space for saving changes. The default casper-rw loop file we used in the Windows USB installation tutorials is only 1GB.
