But .txt is not the same as .rs; yet .txt is not the same as .docx, although both of these files look the same to the human eye.

    Someone will probably correct me – but the funny thing is that stuff like docx and xls are just a zipped/tarballed collection of different kinds of files. So I would add whatever the official term for “zipped/tarballed” to your list.

        Sometimes you can just unzip a .exe file and it’s got a bunch of smaller files inside
        Also Java’s .jar files are literally just .zip files with a different name
        Lots of video files are just a group of files smashed together pretending to be one single file. Like video, audio, subtitles, a little text file with some descriptive info in it…

        Try renaming a docx file extension to zip. Then open the file, you’ll see that there are other files (mostly XML) inside. The docx is a container.
