i download driver but get a directory

[johnny]

Dear Friends,

I just downloaded this driver update Filename: NVIDIA_RIS_V6772.zip.
(i could not attach it for your reference, it is 3.11 MB).

I unzipped it and found a folder but don't know how to take it further from here. This may be a very silly question and I apologize for that, but could somebody please tell me how to proceed?

Thanks a lot.

johnny
