Lenovo laptop D: Drivers?

I have a lenovo y520 laptop with a D: Drive, an SSD with 25 gb. In here is a drivers folder taking up 2gb. I have moved it to the C: drive (windows) as well as backed it up to a flash drive. Is this safe? Will my operating system need the drivers folder?

Find that driver folder that you just moved right click on it find properties and if the properties on that folder are d / drivers change them to c:/drivers then you will be just fine they may have simply been stored on the D drive as storage space but if somebody created a d Drive you do want to check what I just mentioned
