Can I make my PC faster if I store files on D drive?



I have a Dell PC that has started to slow down considerably over the past couple of months. I was looking around for things to speed it up (e.g disc-clean-up, defrag etc) and noticed, rather naively, that the C drive (which is a HDD) is over half full, whereas there's a whole 1TB SSD D drive that is almost completely empty. I imagine there are a lot of quick wins to be hand by switching a lot of things over to the D drive, but I don't know what would be best to move there and how best to do this safely. Many thanks."

Should I save files on C drive or D drive?

So, is it OK to store files on D drive? We can see from the above content that the D drive can be seen as a partition used to store data files, thus, it's highly recommended to leave vital data files and programs on the C drive and store others on the D drive or other drives. As long as there is enough space on the C drive, your computer can certainly run faster.
