ZIPArchive

A 4D ZIP archive is a File or Folder object containing one or more files or folders, which are compressed to be smaller than their original size. Esses arquivos são criados com uma extensão ".zip" e podem ser usados para poupar espaço em disco ou transferir arquivos via meios que tenham limitações de tamanho (por exemplo, um email ou por uma rede).

• You create a 4D ZIP archive with the ZIP Create archive command.
• 4D ZIPFile and ZIPFolder instances are available through the root property (ZIPFolder) of the object returned by ZIP Read archive command.
