I want to be able to have a file extension that acts the same as a different one
for example lets say i would like a file extension called .duffka
i want the file extension to be able to act the same way a .zip and even be read by the same programs a .zip could be
all i know is that you need the reg editor or something

Under HKCR in the registry export the .zip key, then edit the exported file, change the .zip part of the paths to whatever you like .duffka and import the file

You would just need to add it to HKCR. You could even just point it to the zipfile key
