The default install of IDM installs ALL the drivers. I remember myself asking this question years ago in the IDM v3 days, but do those installed drivers count against the JVM heap? I mean even if they are not running, they get loaded right?

So a followup question would be how would one remove all the drivers they do not need? For instance if you have an Engine running on a Rhel server that only needs the eDirectory driver, how could you remove the 50 or so other drivers if that is counting against your memory, etc.
