About ZIP Archives
A 4D ZIP archive is a File or Folder object containing one or more files and folders, which are compressed to be smaller than their original size. These archives are created with a ".zip" extension and can be used to:
- Save disk space
- Store data on a removable media device
- Easily transfer files/folders via mediums which may have size limitations (e.g., email or inter/intranet systems)
4D ZIP archives are created and handled with the following 4D commands:
