How to Get Rid of Junk Files in Windows 10 – Possible Solutions

As to the question of how to delete junk files on Windows 10, there are two options – Windows Disk Clean-Up and third-party programs like CCleaner. Although the basic function of both is to speed up your PC and save storage space, there are certain differences.

Disk Cleanup in Windows does the basic cleaning. It scans C Drive – or, wherever you installed Windows OS – for “useless” files. The basic function of Disk Cleanup is to save storage space.

This tool will take care of temporary files, log files, Windows error files, Internet files, etc. These having said, Disk Cleanup is limited in many aspects, and that’s where tools like CCleaner enters.

One problem with Windows Disk Cleanup is that it does not clean third-party installed programs. We said it would take care of Internet temporary files, but the action is limited to Microsoft Edge. If you’re using Chrome for browsing, there is nothing to help it.

When it comes to CCleaner, the tool would clean up junk files from various programs, including installed ones. It also takes care of some deep areas of Windows OS.

While the choice is yours, you can attain better speeds and storage space with CCleaner. However, in both tools, there are a few common things you can clean. You should know what they mean before you hit the ‘Clean’ Button.

Windows 10 Junk Files You Can Safely Delete

You would find the following options in both Windows Disk Cleanup and CCleaner. We are giving you basic definitions of all the types of junk files. So, when it’s time to delete, you know the one you must and the one you mustn’t.

Recycle Bin Files

When you delete a file/folder, it isn’t permanently erased. Instead, you can find the same files in the Recycle Bin folder. These files will add up to the total storage consumption of your PC. It can, sometimes, slow down the PC as well.

This is the first and foremost thing you can remove safely. You can do it manually, too, by opening the Recycle Bin folder and deleting all the files.

Temporary Files Windows 10/8/7

There are certain tasks going on when you open a particular file – be it Word Document or a movie file. All these tasks may create some kind of temporary files, which are deleted after the task. In some cases, though, some temporary files are not deleted.

This can, in turn, slow down your PC in a pathetic manner. You might have seen these files while working on Microsoft Word or something. They usually have an alphanumerical string as the name. You can safely remove these temporary files – via Disk Cleanup or CCleaner – to free up space and to increase speed.

Files of Previous Windows Installation

How did you get Windows 10 on the PC? Did you upgrade from Windows 8.1? Well, in that case, there would be some old Windows files in the C Drive.

Needless to say, these files will take up a lot of space. These files are used to roll back to the previous version if you want to.

So, if you are sure about not rolling back, you’d be able to delete these files with confidence. This can be removed manually or via Disk Cleanup wizard. You can also use CCleaner if you like.

Web pages Saved Offline

Do you know that your web browser saves some web pages offline? Well, if you visit some websites often, it happens. The core idea is to make the loading quick the next time you open the same website.

While it is a good thing for slow internet connections, these files can slow down your PC and take up space.

So, the choice here depends upon the internet connection you have. If the connection is quick, go ahead and delete all the offline saved files. If you have a slow connection and don’t prefer reloading, leave the box for not clearing.

Temporary Internet Files

Every internet session leaves some files on your System hard drive. Just like other temporary files, they are supposed to get deleted.

However, due to some issues, they may stay on your computer. In that case, you’ll have to manually get rid of all these internet-based files. Just make sure that you’re not deleting useful data like Cookies, Form Info or passwords from the browser.

If you were using CCleaner, you have an option to do this too. This is applicable for all web browsers you use, but Disk Cleanup takes care of Microsoft Edge only.


Haven’t you seen those tiny thumbnails when you open a folder with pictures? These thumbnails are not deleted automatically – another step for increasing speed. However, the accumulation of the same can cause a lot of issues. So, it’s better to remove these thumbnails for the sake of increased speeds. You won’t even notice the difference.
