RoU | BUG: Case sensitivity on Windows system

[Foucoubou]

As known
Unix path is case sensitive whereas Windows is not.

Currently if running on windows and you change case sensitivity in title (and maybe in path too) then the logic says the path is different, but the renaming will fail with error on duplicate file.

Suggestion for fixing - it would be nice to have the filename properly cases sensitive - so the need would be to change the physical moving / renaming part to take that into an account
