Why convert DOCX to ZIP?
Microsoft Word Open XML Documents are ZIP-based Office Open XML packages - the .docx extension is the only distinction from a plain .zip at the file level. Both start with the PK magic bytes (hex 50 4B 03 04). The main reason to access the ZIP structure is inspection: developers extract raw XML, retrieve embedded images, or audit document metadata without opening Word.

Right-click the .docx, copy it, rename the copy's extension to .zip, then double-click - Windows Explorer opens it as a browsable folder with no extra software needed.
