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?

People usually ask "Can I make my PC faster if I store files on D drive?" when they find their computer performs slower and slower because of C drive full and D dive empty. To figure out the answer, you need to understand the basic usage of C drive and D drive.

The C drive is the main partition when Windows operating system is installed for the first time. Followed by other crucial system-related files stored on it, C drive is also called a system partition. When you download applications or programs from the website and don't do anything at set-up stage, they will be stored on C drive by default, together with the Windows system. That's why your computer gets slow if a large number of files are taking up the free space of C drive.

Compared with C drive, D drive is usually a secondary hard drive installed on a computer, often served as the restore partition. For example, you can store your essential files here as a recovery option, if something wrong happens to your computer, you can recover your data from it.

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.
