The first plugin filename DIMG tries depends on the platform. It tries to load DQlibdskdrv
on UNIX platforms or DQWindrv
on Windows. On both platforms it will then attempt to load dqplugin
before displaying a File Open dialog allowing you to browse for a Drive Access plugin.
Unlike with filesystem plugins, this process can be overridden by specifying the plugin name in the DIMG configuration file. For more details on how to do this see Section B.1, DQDriver Location. Should the specified plugin fail to load, DIMG will fall back to the default behaviour (trying the two default filenames before prompting).
