How to delete temporary files in Windows 10 and get more disk space

22 mayo, 2021

Regardless of which operating system you use, with the passage of time many files and data begin to occupy precious space on your hard drive and that they have no use. From those that you decide to delete but never deign to delete from the recycle bin, to all the information that your web browser saves while you browse.

In the case of Windows 10 there are several options already included in the system to deal with this problem, which gets bigger the smaller your hard drive is. Temporary files they can take up many precious gigabytes of space that we would rather have free, especially if we have a nice and fast SSD but not too much space because they are not yet as cheap as a hard drive.

These types of tasks should be done quite frequently to keep your system working as well as possible. If you have an SSD installed in your computer, perhaps you did not know that for it to work optimally it should always have an amount of about 20 to 25% free.

When an SSD has little free space it has a large number of partially filled blocks, and the process of writing information to it will be slower than if it had many empty blocks.

Remove previous versions of Windows

If you are one of the people who upgraded from Windows 7 or Windows 8 / 8.1 to Windows 10, it is possible that those older versions of Windows are taking up a large amount of space on your computer unnecessarily.

It also happened with the Windows 10 Anniversary Update, which was a whole new version of the operating system. This was useful if you planned to go back to the previous version of the system if Windows 10 did not suit you or you did not like it, but that time is already over.


You can do two things: first open Windows Explorer, go to the C: drive and look for the folder Windows.old. right click on it and then on Properties. Look at the space it occupies and decide if you want to delete it. There is no danger in doing this if your Windows 10 has been working properly for a long time and all your documents are in place.

Disk Cleanup

The other option is to use the Disk Cleanup from Windows itself. Just type exactly that in the search drawer after hitting the home button and hitting Enter. Wait for the program to finish calculating and once the options window appears, click on the button that appears below “Clean system files”.

There you will find a large number of temporary files that are no longer needed and that you can delete, including previous versions of Windows if there are any. Check the corresponding boxes and simply press accept.

Delete restore points

Within the same Disk Cleanup tool, next to the option that we just discussed, there is a tab called “More options“, from there we can delete old restore points to free up space.

Delete Restore Points

If you are not interested in keeping those previous states and only the last restore point created with Windows will do. deleting those images can free up a good amount of space. You must be sure, once you click on “Unlock …” only a confirmation message will appear and goodbye restore points.

Storage options

For mysterious reasons that only Microsoft will understand, both from the disk cleanup and from the storage options in the Windows settings menu there are options to delete temporary files. The strange thing about the situation is that if you release everything with one tool, the other is likely to show you different numbers.

The Disk Cleanup may say there are only about 14kb of temporary files to delete, but many GB appear from the drive settings. That is why you should also use this tool.


Press Windows key + I to open the settings menu. Choose System and later Storage. There choose your disk and wait for Windows to load all the sections and show you how the space is distributed on that drive.

This Equipment Configuration

It is very important that you pay attention to the last two options, as these include the temporary files that you will definitely want to get rid of, just be careful with the “Downloads” section, as this includes everything you have ever downloaded and is in that folder from the system, you may not want to delete that.

Temporary files

The section called “Other” includes things that Windows doesn’t quite know in which category to put. You will have to review them manually and decide which ones you can do without.


If you want a tool that does everything we did in the previous steps and helps you save time and a lot of clicks, then you could try CCleaner. As its name implies, it is a cleaning tool, and although it does much more than that, remove garbage that accumulates in Windows It’s your specialty.

Piriform Ccleaner

Simply download and install the program (it’s free), run it, and select the “Cleaner” option. Once you press the “Analyze” button, CCleaner will search for temporary files in all browsers that you have installed: Edge, Opera, Firefox, Internet Explorer, and Chrome. It will also search for temporary files from Windows Explorer, system, and some advanced functions.

At the end it will offer you an analysis and tell you how much space can be freed up. If you run the cleaner everything will be removed and you will have your precious megabytes back in a few seconds.

System Ninja

A good alternative to CCleaner is the System Ninja tool that we talked about recently. Like the first one, this one has a “Garbage scanner“which looks for all kinds of temporary files in Windows that can be deleted to free up space. Besides this it also has an option to help you find duplicate files.
