A: Apple reviews every tiny update before posting it to the App Store. And this review process usually takes between one and two weeks. I submit BetterZip to Apple on the day I release it on the web. Please be patient, it will appear in the App Store.

A: If you are using a free e-mail 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.

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

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.

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.

A: The Pages document is actually a zip file. When you drag it into an empty window, BetterZip thinks that you want to open it and shows you the contents of the zip file instead of adding it to an empty archive. Hold down the command key while dropping a Pages document or any other archive into an empty BetterZip window. This will force BetterZip to add the file.

A: You have probably received a new Word docx file, and use Word 2004. You should not extract such files, but instead get the Microsoft file converter from here. Install the converter and run your files through it. For further support with this, please contact Microsoft.

A: This is due to the way these formats work: First an uncompressed tar archive is created then this tar file is compressed with BZip2 or GZip, which are both limited to compressing one file. So, tar has no knowledge about the compression factors while GZip and BZip2 don't have knowledge about the contents of the tar file.

A: You can turn that off in the preferences. Go to the tab Presets and uncheck the option Reveal destination in Finder after extraction for the service preset.

A: Delete BetterZip.app from your Applications folder. Open the folder Library/Preferences in your home folder and remove the file com.macitbetter.betterzip.plist. That's all.
