The goal of the assignment is to add functionality to the menu which will restore the archive to a location on your computer which you specify. In terms of the menu, three items are necessary.
1. Functionality which permits the user to enter the path on the computer which points to the directory where you want the restoration done.2. Functionality which restores the archive to the location specified in 1 above.3. Functionality which permits the user to specify, from a list in the archival restoration, but just a few of the files.I already have a python txt file with other function. I also have a menu in the txt file. so I want these 3 items to be in my original menu. My computer is a MacBook and I am using WinZip to unzip files. The program has to work on MacBook and WinZip.
