Difference in archive formats?
Archive Utility Preferences
Use archive format:
- Zip archive: A Zip file (
.zip). - regular archive: ASCII cpio archive (
.cpio). - compressed archive: An ASCII cpio archive, but gzip compressed (
.cpgz).
Note that the Compress "folder" option in Finder always creates a zip file. To use the other options you have to open Archive Utility directly and drag-and-drop things onto the icon in the Dock.
