The two NVIDIA driver folders are the places where the old drivers you installed before have not been deleted, and the drivers of the driver wizard are all backed up, so you install and save them on drive C, so it takes up two or three grams of space. You'd better not delete this. Xu Fei, you know the old driver version and the current driver version. If the capacity of drive C is enough, just install the driver wizard on other drives in the future.
