Unzip error "End-of-central-directory signature not found"

I have a ZIP file that open in Windown/MS Word, (actually it is a .DOCX file). Opening it with LibreOffice / Mac produces:

General Error. General input/output error. 

File says:

../Commission Plan.docx: Zip archive data, at least v2.0 to extract 

And unzip says:

Archive: ../Commission Plan.docx End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in one of ../Commission Plan.docx or ../Commission Plan.docx.zip, and cannot find ../Commission Plan.docx.ZIP, period. 

How do I open this file?

Use this alternate zip process to uncorrupt your file. (Idea based on answer at )

mkdir DOCX cd DOCX jar xvf ../Commission\ Plan.docx jar cvf ../Commission\ Plan2.docx * 

This will decompress and recompress using the superior zip utility build into the java runtime on your system.

Unzipping with 7z worked for me:

7z x COCR2_100.zip 

Install via APT with apt install p7zip-full.
