Generally speaking, slow computer performance is common to see especially after years of constant use. This can be caused by different factors and one of them is C drive full issue. C drive is also know as system drive where the OS is saved. So, when your files are constantly consuming the free space of C drive, your computer becomes certainly sluggish and slow, and even worse, runs into frequent system crashes or meets other common PC errors. Therefore, it's necessary to clean up your C drive regularly to make your PC run faster.

2 common ways to clean up C drive

In order to help users prevent the "PC suddenly slow" problem, Windows has been featured with several methods to free up space from C drive. The two popular and common ways are presented as follows.
