I am using linuxmint 11 on usb (8GB). I am formatting it using LiLi usb creater. but in anyway it keeps around 4GB for persistent storage.
Anyone know how to utilize full 8GB of the USB for persistent storage.

Also, if i want to install some applications (amarok, chrome, skype) in different partition how can i give the customized path. I know how to do it by compiling source code, but how to do it with apt-get
