How to Clear Temp Files in Windows 10: A Quick Guide
Windows 10 creates temporary files while you use certain apps to speed up certain processes. However, your PC can create hundreds of temporary files in a day, which take up hard drive space and slow down your computer. For example, an open Microsoft Word document creates a temporary copy of the file every few minutes!
This wikiHow will show you how to clear temporary files from your Windows 10 PC using Disk Cleanup, the Settings app, and simple commands in the Run dialog.
Things You Should Know
Temporary files are mostly harmless, but can fill up your hard drive and make your computer run slow.
Delete temporary files using the default built-in program called Disk Cleanup.
You can also manually clear temp files using the Settings app and Run dialog commands.
Method 1: Using Disk Cleanup
Open Disk Cleanup. Search “disk cleanup” in the taskbar’s search box and click the first result, which is the Disk Cleanup app. This is the easiest method for cleaning up temporary files on your Windows 10 computer. You can also press the Windows key + S to open the search function if you can’t find it in the taskbar.
Click the drive you want to clean. The drive you use the most will have the most temporary files.
Click OK. This will confirm your drive choice.
Click to check the boxes next to "Temporary Internet Files" and "Temporary Files." You’ll see how much space they will free up along the right side of the columns. Suggested boxes to delete are checked by default; you can leave these checked and delete these files or you can click to uncheck the box and not delete these files.
Click OK. This will confirm the deleting action. When you continue, that box will disappear and you’ll see a progress bar of the deletion, which will disappear when it’s done.
Method 2: Using Settings
Open your Windows Settings . You can click on the Start icon and then the gear to open Settings.
Click System. It's the computer icon.
Click Storage. This is near the bottom of the menu on the left.
Click the drive where Windows 10 is installed. It usually has a Windows logo over the drive icon and might be called “This PC.”
Click Temporary Files. The number here represents how much space the temporary files are taking up. The next page shows you all the files that are considered temporary files, including files in the Downloads folder, files in the Recycling Bin, and thumbnails.
Click to check the boxes next to the files you want to delete.
Click Remove files. You’ll see a progress bar of the deletion.
