Exporting the previous version of a file type configuration
Starting with version 11.7, WorldServer stores the previous version of each modified file type configuration, as well as information about who modified it and when. You can use the previous version of a file type configuration to compare it to the current one or to restore it in case the current one is not working as expected. Keep in mind that the previous version is available only for export; in all other scenarios related to file type configurations, only the current version can be selected and used.
