This may have broken the connection between the source of the download and your Mac.

If you think an incomplete download is the cause of your error, try downloading the file again.

You need permission to expand a zip file. If you downloaded the file from a website, it probably didn’t have permissions. If you received the file from a non-public source, ask them if there are any special permissions for the zip file. Then they have to give you permission and resend.

File size

If the compressed original file is too large, your Mac will not be able to decompress it. You’ll have to use your Mac’s Terminal to expand huge files. See the additional sections below to find out how to use the terminal to expand large zip files containing error codes.

Incomplete Compression

If the original compression was done incorrectly, you may have problems expanding a zip file. Common factors that can interrupt a compression are if the computer is suddenly turned off, there is a power failure, or if the file is moved from its original location.

If a failure occurs during the compression process, the file will be damaged. Unfortunately, there is no way to repair a zip file damaged during the compression process. You must revert to the original file and restart the compression. This should solve the problem.

Fix error 22

When trying to expand a zip file, some people get a common error: “Error 22-Invalid argument.” This error is usually caused by junk files interfering with your computer. The best way to deal with unwanted files is to delete them. You can fix Error 22 by deleting the caches on your Mac. Use the following steps:

  1. Launch the Finder window and click “Go”.
  2. Select ‘Go to folder’.
  3. Type “~/Library/Caches” in the text box and press Enter.
  4. A series of folders will appear on your screen. You have to click in each folder and delete the files there. Do not delete the folder itself as it may cause errors in your apps.

Once these files are cleared, the file should be expanded. If there are too many folders to delete manually, you should invest in a program that automatically deletes these files. Many of these programs can all be set to routinely clear the cache, which can help prevent future errors.

Unable to Extend Zip File on Mac – Permission Denied

If you got an error saying “Permission Denied” when you tried to expand a file, you probably can’t access that file. The original user who compressed the file must give you permission to extract the file. If you know you have permission to open the zip file, try moving it to another folder. Expanding a folder in a server folder can cause this error if you only have access to read the folder. Move the compression file to your desktop, where you can read and write files stored there. This should solve the problem.
