That's probably because there is a ctrl-Z (ascii 26) somewhere in the zip file. When you renamed it to .txt, it got treated as a non-binary file and only the contents upto the (first) ctrl-Z got processed. When you appended an 'a' to it an ran it again, the same thing happened. Only the first part of the data to the first ^Z was processed. Hence the md5 didn't change.

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.
