- Adobe Acrobat not installed, I use MuPDF
- Embedded document simply not “really” embedded but just an icon
There is an easy solution. Microsoft Word 2007 documents are just zip-files. Just look at output of
7z l WordDocument.docx
word/embeddings contains the embedded files, regardless of its type.
By the way, LibreOffice/OpenOffice files are also just zip-files.
