This is Windows 7 and I am afraid that a new software will break something (call me paranoid)

While this is very crude and not intelligent at all, it may serve as a start, to at least eliminate the identicals and point out those where differences are minor.

I vaguely recall that FC.EXE had a limitation on the line length -- I'd seen it report differences on lines within text files that were longer than a certain length but were otherwise identical.
