The ZIP64 format was created in part to remove the size limitations of the standard ZIP format.

If your downloaded content is compressed in a ZIP64 format, it should be compatible with all recent Windows and macOS versions and you should be able to open it just like any other ZIP file.

However, some older Mac OS systems may not be able to open this file, in that case, a third-party application might be necessary. For example, The Unarchiver could be a viable option.
