You misunderstand. If I do

copy foo.txt bar.txt

[download]
I will have two files that will produce the same checksum. Clearly they're not the same file (different name, different bits on disk, etc.) yet any test using a checksum will show no difference.

That's what I meant by testing contents rather than testing files.

Do not rebuke them with harsh words ... but rather lead them gently - with URLs - so that they may learn wisdom.
