Due to the extreme sizes of some of the zip archives (often well in excess of 4GB), we recommend using a dedicated zip archive application, such as 7-zip, to open and extract these datasets. For example, the built-in zip archive handling in Microsoft Windows (ie Right-click to 'Extract Here') is not designed to handle these sizes and will throw errors, even suggesting (falsely) that the archive is corrupt.
