With active use of the computer, it is easy to notice that free space on disks (partitions) becomes less and less. To solve this problem, the user needs to perform certain actions.

Before you start freeing disk space, you first need to look at what is taking up disk space. You need to figure out why the space on the “C” drive is taken.

Too Much Disk Space Used: Causes of This Situation

Most often, users are faced with a lack of space on the system drive “C:”. We need to find out what is taking up disk space in order to decide what to do with it next.

In the Windows operating system, the following data can take up a lot of disk space:
