2. Frequently Asked Questions

Registration and Registration Keys

Q: I purchased BetterZip 2 in the Mac App Store. How can I upgrade to BetterZip 5?

A: Forward me the invoice email you received from Apple and I will send you a temporary key that lets you upgrade to BetterZip 5 for the discounted price of $14.99.

Q: I haven't received my key after I bought BetterZip.

A: If you are using a free email service like GMail, your transaction may be subjected to extended fraud checking, which is required by credit card companies. If your key doesn't arrive within 8 hours, please contact me.

Q: My registration key doesn't work.

A: Please, make sure that you copy the complete code (four lines of numbers and letters, possibly ending with an equal sign) into the text field in the registration window.

Compression and Extraction

Q: I want to extract an archive, but BetterZip asks for a password. What's that about?

A: The archive's creator probably encrypted the archive and protected it with a password. Ask the creator for the correct password. In rare cases the archive is corrupted, but BetterZip cannot recognize this. If you downloaded the archive from the Internet, try downloading it again. The password has nothing to do with the BetterZip registration code.

Q: I compressed a PDF, JPG, MP3, MOV, or AVI file, but the compressed file is not much smaller than the original file. What's wrong?

A: Nothing is wrong. Multimedia files like music, images, and videos are usually already compressed as good as possible. Compressing them with an archiver cannot squeeze out many more bytes from the file.

Other Questions

Q: The Check for Update menu command fails with "BetterZip can’t be updated when it’s running from a read-only volume like a disk image or an optical drive", but it is installed in the Applications folder.

A: Depending on how BetterZip was installed, the macOS quarantine extended attributes might still be set on the included update helper program. This is not specific to BetterZip, but other auto-updating apps as well. It's a (somewhat annoying) security feature of macOS. To clear the quarantine follow these steps:

  1. Quit BetterZip.
  2. Start Terminal.app from the Utilities subfolder in your Applications folder.
  3. Copy and paste this command into the Terminal.app window and press ↩︎ (Return):
    sudo xattr -dr com.apple.quarantine /Applications/BetterZip.app
    When asked enter the administrator password.
  4. Quit Terminal.app and try updating BetterZip again.

Q: How can I uninstall BetterZip?

A: First, disable the Finder button extension (only macOS 10.14 and older): Go to BetterZip > Preferences > General and uncheck the option "Show BetterZip button in Finder windows". After that quit BetterZip and move BetterZip.app to the trash. If you chose to add BetterZip services to the Services menu (including the Finder's contextual menu), you may want to remove these from the folder Library/Services in your home folder. Lastly, open the folder Library/Preferences in your home folder and remove the file com.macitbetter.betterzip.plist.

Q: I want to translate BetterZip into my language. But how?

A: Please contact me by email and I'll send you the necessary files. Thanks!
