Zip is a commonly used compression file format. It reduces the amount of space needed to store data which can free up valuable space on a hard drive. It is also efficient when transferring content over a network or the Internet. Many external utilities can be used to perform a Zip file compression. However, the ability to compress files and folders into Zip format has been natively available through 4D language for quite some time. This technical note demonstrates a unique implementation around the native Zip file compression feature to create a Zip utility that can be used in any 4D solution.
