many of us are using ubuntu. for various circumstances sometimes it becomes important to re-install the operating system. this makes our all installed and update files over written. so, we have download them again and re install them.i think this is a painful task and if the net speed is slow then it can be time consuming too...
but ubuntu takes care of the problem. only 3 command and couples of minute can solve the problem. all you have to do is open the terminal and follow the commands below.

backup applications:-

sudo apt-get install dpkg-repack fakeroot

mkdir ~/dpkg-repack; cd ~/dpkg-repack

fakeroot -u dpkg-repack `dpkg --get-selections | grep install | cut -f1`

re-install applications:-

change directory and go to the location where the dpkg-repac is kept (ex:- cd /....../dpkg-repac) then give the following command in a terminal-

sudo dpkg -i *.deb

----------------------------------------------
this will create a folder called dpkg-repack in your home folder. in that folder you will find .deb file of all installed applications in your pc. you can move the folder to any location you want.
