This shows the location of the folder ITPWork. This folder contains the (sub) folders used by ITP/Server to store and retrieve files. Not all files used by server are stored here - notably log and temp files can be set per machine - but files like scripts, models, DIDs etcetera are.
Because every ITP/Server setup has its own ITPWork folder, the name you provided at install for the set-up is used in the name of the folder; its full name is ITPWORK [ITP/Server set-up name provided].
