Zip Files Not Opening on Mac: Troubleshooting Common Issues

If you're experiencing issues with opening zip files on your Mac, you're not alone. Many users have reported similar problems, and in this article, we'll delve into the common errors that can occur when trying to extract or open zip files.

The first error many users encounter is the 'Headers Error' and 'Unconfirmed start of archive' warning. This is often accompanied by a cyclic redundancy check failure on an extracted file. This issue can arise due to corrupted zip files or incorrect extraction methods.

To troubleshoot this problem, you can try extracting the file using terminal commands. For example, if you're using 7-Zip, you can use the command: `7z x file.zip`. If this doesn't work, you may need to reinstall the 7-Zip application.

Another common error is 'There are data after the end of archive.' This warning often appears when there's an issue with the zip file itself. In such cases, try re-downloading the zip file or checking for any errors during the download process.

When using your operating system's (macOS) built-in archive manager to extract a zip file, you may encounter an error dialog stating 'An error occurred while loading the archive.' This can be frustrating, but there are ways to resolve this issue.

One possible solution is to use the web client of OneDrive to download the contents of the folder. This may help avoid any potential issues with the zip file itself or your operating system's extraction methods.

In conclusion, if you're experiencing issues with opening zip files on your Mac, try extracting them using terminal commands or re-downloading the zip file. Additionally, consider using the OneDrive web client to download the contents of the folder. By following these troubleshooting steps, you should be able to successfully extract and open your zip files.
