Hi Amith,
I know this isn't the answer to your question, but have you considered reaching out to whomever is zipping the files? If they're within the organization you're making an automation for, you could ask them to use another method to zip the files. Sometimes the solution to an automation problem is to avoid the problem entirely by adjusting the non-automated portions of the process to decrease the difficulty of the automated portions.
Is there any chance of getting that changed?
Respectfully,
Dave
