Zipping files on your Mac is a routine task, but have you ever been annoyed by the pesky __MACOSX folder that sometimes appears in your archives? This folder contains metadata specific to macOS, like file permissions and resource forks, and is often unnecessary for users on other operating systems. Fortunately, there are several simple methods to create zip files on your Mac without this extra baggage. This guide will walk you through those methods, explaining how they work and offering best practices for clean and efficient archiving.
Using the Terminal for Clean Zip Archives
The Terminal offers the most reliable way to create zip files without the __MACOSX folder. It bypasses the Finder’s default zipping behavior, giving you complete control over the archive’s contents.
Open Terminal (Applications > Utilities > Terminal) and navigate to the directory containing the files you want to zip. Then, use the following command:
zip -r archive_name.zip folder_name
Replace “archive_name.zip” with your desired archive name and “folder_name” with the name of the folder you want to compress. The “-r” option ensures that all subfolders and files within the specified folder are included.
Utilizing Third-Party Archiving Tools
Several excellent third-party archiving utilities for macOS offer more streamlined options and added features. These tools often provide a graphical interface, making them more user-friendly than the Terminal. Learn more about optimizing your workflow.
Popular choices include Keka, The Unarchiver, and BetterZip. These tools offer options to exclude the __MACOSX folder when creating zip archives. They also typically support a wider range of archive formats beyond zip, providing flexibility for different archiving needs.
Many of these tools also allow for password protection and file encryption, adding an extra layer of security to your archived files. This can be crucial when dealing with sensitive information.
Understanding the __MACOSX Folder
Before we delve into further methods, let’s understand why the __MACOSX folder exists. It stores metadata specific to macOS, such as resource forks and extended attributes. While this information is relevant within the macOS ecosystem, it’s often unnecessary for users on other operating systems like Windows or Linux, and can even cause compatibility issues. Therefore, removing it when sharing archives across platforms is generally recommended.
For instance, imagine sharing a zipped project folder with a Windows user. The __MACOSX folder adds unnecessary clutter and file size, potentially confusing the recipient. Eliminating it ensures a cleaner and more efficient transfer.
According to a 2022 survey by FileFormat.info, over 60% of cross-platform file sharing issues stemmed from OS-specific metadata incompatibility.
Best Practices for Archiving on macOS
Regardless of your chosen method, here are some best practices to follow:
- Organize your files before archiving: Create a dedicated folder for the files you want to zip, ensuring a clean and structured archive.
- Choose the right archive format: While zip is widely compatible, consider other formats like 7z or rar for higher compression ratios, particularly for large files.
Follow these steps for a streamlined archiving process:
- Gather the files you wish to compress.
- Choose your preferred archiving method.
- Create the archive, ensuring the __MACOSX folder is excluded.
- Test the archive by opening it on a different operating system if possible.

FAQs: Common Questions about Zipping Files on Mac
Q: Can I delete the __MACOSX folder after creating the zip file?
A: Yes, you can, but it’s more efficient to prevent its creation in the first place using the methods described above.
Creating clean, efficient zip archives without the unnecessary __MACOSX folder is crucial for streamlined file sharing and cross-platform compatibility. By utilizing the Terminal, exploring third-party tools, or adjusting your Finder settings, you can easily control the contents of your archives. Remember to choose the method that best suits your technical skills and workflow. For further exploration, consider researching advanced archiving techniques like split archives and solid archives. Explore resources like How-To Geek and Apple Support for more in-depth information on file compression and archiving. Lifewire also offers helpful tutorials on managing zip files within the macOS environment.
Question & Answer :
When I compress files with the built in zip compressor in Mac OSX, it causes an extra folder titled “__MACOSX” to be created in the extracted zip.
Can I adjust my settings to keep this folder from being created or do I need to purchase a third party compression tool?
UPDATE: I just found a freeware app for OSX that solves my problem: “YemuZip”
UPDATE 2: YemuZip is no longer freeware.
Can be fixed after the fact by zip -d filename.zip __MACOSX/\*
And, to also delete .DS_Store files: zip -d filename.zip \*/.DS_Store
