This question comes up frequently because some of the US Data and Spatial datasets are HUGE and we want to ensure there's enough hard drive space available. To help users better anticipate hard drive requirements, file sizes are included on the installation media in the Documentation folder of the update in a Excel worksheet. The .xlsx is titled Alteryx Qx 201x Variable List and includes file sizes for the United States and Canada in a worksheet labeled File sizes. File sizes reflect the installed file size.
