"I started to feel ignored by the monks "

"feel ignored" ? ... in just under two hours?

That may reflect a misunderstanding of how the Monastery works... especially when the question was less than crystal clear (judging by your need to clarify.)

We're here to help, but the 'free-help' and 'instant-help' domains are not always co-terminus. Have some patience, mhd.tahawi, and recognize that the good Monks are not always instantly available to solve your problems.

And consider, also, the possibility that reversing the workflow you specified ("create a big archive and then rename member files") would solve your problem without needing to do renames inside the zipfile.
