File formats that actually are the regular ZIP archives

Some file formats are actually the regular ZIP archives

Half of the files we use for translation are actually regular ZIP archives with a modified extension. This means that there is no point in archiving them, because they are already archives. But if you change the extension to ZIP and unzip them, you’ll find some interesting things inside.

Below are some file formats that only pretend to be regular files but are actually ZIP archives.

• DOCX—Word
