I found on my program files(x86) folder a subfolder called AGEIA TECHNOLOGIES, and inside it, it has a lot of subfolder named with various version of ageia drivers, from v2.3.1 until v2.8.1 and there is a document that says "DO_NOT_MANUALLY_DELETE_ANY_SUBFOLDERS". The problem is that I dont have an ageia physx card, and why do I have this folder? It is installed by the nvidia drivers?because the nvidia drivers install a physx package but Im not sure if it is the same than the one Im talking about. Can you tell me wether or not is safe to delete those folders? because in the control panel in the section of uninstalling a program there isnt any program related to Ageia Techonologies, only the physx drivers that came with nvidia, but are they the same?
