Help! My C drive is running out of space and my PC is extremely slow nowadays. Can I move Program Files to D drive so that I can make enough space for the OS?
Why change Program Files to D Drive?
Generally, when we download an app or other program from the internet, it will be automatically stored in Program Files or Program Files(X86) folder in C drive by default. In this case, over time, the storage space of the system drive could become smaller and smaller which can result in quite a lot of problems including very slow system speed, frequent system crash and low disk space warning.
So, under this circumstance, it’s quite necessary to free up C drive to keep the OS in the best state. In this holistic post, I’ll provide some techniques to help change Program Files to D drive efficiently when the system partition is running out of space.
