The compiled html help files are maintained by Cove Systems and they are normally stored in the Cove/Help subdirectory on the system running the application. This can be the local windows workstation or a network server depending on how you have installed the applications and configured your system. When a help or chm file is updated, or a new help file is released by cove, you can install the updated or new file by merely overwriting or installing the file in the appropriate help directory.
