I have come across a new software called
ALZip which has a format called "[COLOR="rgb(0, 100, 0)"].egg[/COLOR]" which is really powerful compressing format
Check this out:

I had tried several files,all showed great compression ratios.
But i was not able to find out a way to incorporate it with install script fonts or even the command prompt way.
If anybody can incorporate it with ISS then all those "arc+srep+precomp" method which takes hell lot of time can be skipped and game conversion can be made more easy...........
