Compare files by their contents

[Filprots]

Hello! Thanks for this awesome module!
But i thought it will be much more helpful, if it could compare files by it's contents. How do you think?
Is it hard to implement?

OMG I have not seen this issue for nearly two years. No I do not think that it is difficult to implement. Just calc a checksum on the file and compare it, or compare then contents directly. Feel free to try an implementation, I support you with finishing :)
