This folder contains the BlueZone CAB files which are a series of compressed files that contain each BlueZone emulation client, as well as other files like help files, that are associated with the emulator. For example, the bzmd.cab file is the BlueZone Mainframe Display cab file.
There is a cab file for each BlueZone emulator as well as a Scripting cab that contains scripting and HLLAPI related files.
We use compressed cab files in BlueZone Web-to-Host to keep the file download as small as possible.
Cab is short for "Cabinet" file which is a Windows compressed file.
