Once you've checked the size of the file and found it to be the same as an existing file, if you read a 32-bit word from the middle of both files and compare them, it will eliminate the need to run a full md5 checksum in 99.999999977% of cases.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
