If you already use WinISD, bring your own drivers across. Pick the .wdr files you want and they become drivers here. Nothing is uploaded anywhere else, and Baffle does not redistribute anyone's database. These are your files.
.wdr
Select as many as you like in one go. Where WinISD keeps them depends on the version: commonly %APPDATA%\Linearteam\WinISD\Drivers.
%APPDATA%\Linearteam\WinISD\Drivers
Preview first. A driver already here is listed and skipped rather than added twice, which matters because most people's library is the one that shipped with WinISD, and a good deal of it is here already.
