I'm looking to clean up my HDD a bit and I found that all the old NVIDIA drivers are still in there. Is it ok to delete previous versions and keep only the most recent?
All you need to do to clean NVIDIA drivers is preform a clean installation of the drivers when installing newer ones. Download the newest drivers if havent already. Youll be prompted to do a "Advanced" or "Custom" installation. Choose "Custom" and what that will do is remove all previous drivers and install the newest one.
