Need help to unzip response from postman API

I fire an POST API in postman which is a file upload and the response is also a file (zip or tar).
I need to unzip or untar this file so as to use that data in the next api .Both api’s are part of a collection.
These are a few headers in response
Content-Type →application/octet-stream

content-disposition →attachment; filename=xxx.tar

content-transfer-encoding →binary
