Many times there is a need to break up HUGE files to make them more manageable and faster to download the pieces of files rather than one huge download. I have used a couple of programs to combine and create ISO files of my own. The programs I use are PowerISO and MagicISO.
There are free versions to try, however the real benefits come from the FULL paid versions that allow large file importing and work with many iso formats in use today. If you need a more detailed instruction of where to get and how to use these programs, let me know and I will make a Hub out of it.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
