Portal and data collector files retrieved using the Support Tools function are archived as {{.zip.xz}}. This format is used to minimize the disk space required on the portal and collector plus minimize network transfer time.

The format {{.zip.xz}} is not natively supported by most platforms, but there are standard tools available to process them. On most platforms it will be necessary to first extract the uncompressed {{.zip}} from the {{.xz}}, and then extract the files from the {{.zip}}. This means that the system on which the files are being extracted will need free disk space equal to approximately twice the size of the uncompressed files.
