Zip files don’t unzip Mac OSX

Problem

When unzipping a file in OS X rather than unzipping the files it creates a new file with extensions likefilename.zip.cpgz.

Cause

This is a wonderful quirk of zips and compressions. This can be caused by a corrupted file from the download site or an incomplete download, or simply an unrecognized type of compression.

Solution


  1. Right click the zip file and select ‘open with’ there should be one or two options available ‘stuffit expander‘ and ‘archive utility‘ try both of these. If you’re still out of luck continue…
  2. Download a different zip program, www.kekaosx.com. Install and try from step 1 again.
  3. If that still doesn’t work then try the terminal solution.
