sa := TCkStringArray.Create(Self);
success := sa.Append('*.bak');
success := sa.Append('*.tmp');

// Tell the zip object to use these exclusions:
zip.SetExclusions(sa.ControlInterface);

// Append a directory tree.  The AppendFiles does
// not read the file contents or append them to the zip
// object in memory.  It simply appends references
// to the files so that when WriteZip (or WriteZipAndClose,
// or WriteExe, etc.) is called, the files are compressed
// and encrypted.
recurse := 1;
success := zip.AppendFiles('/temp/a/*',recurse);

success := zip.WriteZipAndClose();
if (success <> 1) then
  begin
    Memo1.Lines.Add(zip.LastErrorText);
    Exit;
  end;

Memo1.Lines.Add('Zip Created!');
