Arbortext Editor (version 5.4 F000 and later) is capable of downloading a zipped custom directory structure using HTTP, extracting its contents to a temporary file system location, and using that as a custom directory. This allows administrators to store Arbortext doctypes and other customizations in Windchill.

Windchill makes the zipped custom directories available by designating a special anonymous access folder whose contents will be made available over anonymous HTTP. The HTTP access is anonymous so the user is not presented with an unexpected credentials prompt during Arbortext Editor startup.
