When you run the Notes Gateway, it accesses some standard Lotus Notes 5.x or 6.x files. It also creates and updates some files in the Notes system.
If you are using Lotus Notes 4.x, see Notes Server Directory Structure for Lotus Notes 4.x.
The lotus directory on the Domino server is the root directory for a Lotus Notes 5.x or 6.x system.
The domino directory contains subdirectories and files pertaining to the Domino server. Lotus Notes 5.x and 6.x include the Domino server. Lotus Notes 4.x does not.
The notes.ini file is the Domino server initialization file used by Lotus Notes 5.x and 6.x. You must manually update the notes.ini file to add the Notes version of the GroupWise Address Book to the Notes system, as described in Adding the GroupWise Address Book to Notes.
The data subdirectory contains files used by the Domino server.
The names.nsf file is the Notes public Address Book.
The wpnames.nsf file is the Notes version of the GroupWise Address Book that is accessed by Notes users when sending messages to GroupWise users.
The notesgateway.nsf mail file is the Notes mailbox that belongs to the Notes Gateway foreign domain. It is used for communication between the Notes system and the GroupWise system. See Defining the GroupWise System As a Notes Foreign Domain.
