Checksum to detect Duplicted files and Re-named files?

Yes, but you should use such checksum algorithm that can be used to generate fingerprints for your files. All checksums are not suitable for this.

Well, in general yes. It depends what sort of Checksum you're using though.

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.
