I figured out the problem. When zipping files in windows using winzip, it doesn't explicitly count folders as a "file/folder" as a file in itself.

Eh. All you did so far was noticing that the ZIP contains such a file, and create a File instance (= filename) of the same name.

If you are merely opening the files in Windows, then you can choose what program/application to open them with yourself (though it won't stick for the next time).
