How to free up wasted space with Disk Cleanup, in Windows

When I want to tweak different aspects of the operating system, I generally prefer to use the built-in tools provided by Windows. All modern versions of Windows and especially Windows 10, provide some great tools you can use. One such tool is the underrated Disk Cleanup , which allows you to free up space on your partitions and safely remove even system files that you no longer need. Let’s see how it works and why it is one of the best tools for cleaning up space in all versions of Windows:

How Disk Cleanup works in Windows

Disk Cleanup or cleanmgr.exe is one of the best Windows programs for removing unnecessary files and freeing up space. It is one of the best tools for the job because it is not as invasive as many third-party tools that promise the same thing. Those tools may remove files that are required by certain apps in order to run well and they also tend to dig deep into the Windows Registry and remove entries that may be useful to the operating system. Instead, Disk Cleanup only removes files that it is 100% sure that are not required by Windows or any of your installed apps, in order to run correctly. When analyzing your disk space, Disk Cleanup looks for temporary files that can be removed, for the files that you have already moved to the Recycle Bin (signaling that you don’t need them anymore), a variety of system files that Windows can run without, offline webpages, setup log files and so on. If you want to reduce the number of unnecessary files on your HDD or SSD, to free up disk space and help your Windows computer or device run faster, we highly recommend that you use it.

One thing that you should remember about this tool is that it works best when used on the partition where Windows is installed. If you use it on other partitions, it only removes the files and folders that are found in the Recycle Bin. Therefore, using it on partitions other than the “C:” drive is not that efficient.

The Disk Cleanup tool is located on the disk, in the following folder: “C:\Windows\System32\”. Before using it, let’s see how to start this tool in Windows 10, Windows 7 and Windows 8.1.
