Can I change the program file location on Windows 10? Sure. This post covers five ways to help change program files to solve C drive low disk space errors. There are two folders on the C drive - Program Files and Program Files (x86). As a standard, 32-bit software is mainly developed in Program Files (x86), while 64-bit applications are placed in Program Files. If you load many applications, these two Program Files can take up a lot of storage space.

Over time, the C drive (which is also the boot drive) may become full, and as a result, the performance of your computer system will be seriously affected. It starts running slowly, becomes sluggish and unresponsive, and often even prompts you with a low disk space warning. This is why you should change the program file location from C to D or another drive.

In this post from EaseUS Software, you can learn five ways to change the Windows 10 default program file location.
