My windows\system32\DriverStore\FileRepository is 48 Gigabytes in size.

That is way bigger than I have ever seen anywhere else, and is way of of proportion for a 128GB SSD.

I know how to list the files in it, and I know how to delete them individually.

What I do not know is Which drivers are unnecessary, and which can I delete?

Any clues on how I can find that out would be much appreciated.

Windows 7, Home premium, Service pack 1, fully up to date.

Windows Disk Cleanup and PrivaZer have not reduced the file size.

EDIT:

Techie007 has very rapidly responded to say that this answers the question:

How do I delete folders from the Windows 7 DriverStore?

To my mind, it does not.....It does not (as far as I can see) address the core issue of my question: How do I know a driver in the driver store CAN be safely deleted?

The question  How do I delete folders from the Windows 7 DriverStore? is not a duplicate of this one because it does not ask How do I know a driver in the driver store CAN be safely deleted?
