5 Ways to Remove Junk Files from Windows 10 PC/Laptop

The longer you use your computer, the more junk files it accumulates. This is especially true if you do not clean it up regularly. Having too many junk files will consume valuable hard drive space and even slow down your computer. So, in this piece, we will show you how to remove junk files from a Windows 10 PC or laptop. There are five ways for you to choose.

Way 1: Get rid of junk files by emptying the Recycle Bin

When you no longer need a file, you usually right-click it and then select Delete to delete it. But in fact, the deleted files do not disappear from your computer immediately, but are temporarily moved to the Recycle Bin and continue to occupy your hard disk space. If you never empty the Recycle Bin, the junk files stored in it can accumulate up to several gigabytes over time. Therefore, empty the Recycle Bin regularly. This is an effective and effortless way that allows you to get rid of unnecessary junk files from your computer in time.

Way 2: Delete system junk files using command prompt

When your Windows 10 system is processing tasks, the system itself and some applications automatically create temporary files in the background. These files are for temporary use only. When they are no longer needed, they become junk files, and the system does not automatically delete them. Therefore, you need to delete such junk files manually. Follow these steps.

Step 1: Run Command Prompt as administrator.

Step 2: Type del/q/f/s %temp%\* and hit Enter. Command Prompt will delete all temporary files except those currently in use by the system.

Way 3: Remove junk files with Disk Cleanup

The Windows system generates more types of junk files apart from temporary files, such as Windows upgrade log files, offline webpage caches, etc. So, Microsoft designs the Disk Cleanup tool in all versions of Windows 10 to help you remove various junk files in one go. Here are the steps.

Step 1: Type disk cleanup in the search box on the taskbar, and then hit Enter. This will start the Disk Cleanup app built in Windows 10.

Step 2: Disk Cleanup will ask you to select the drive you want to clean up. Since system junk files are generated on the OS drive by default, just select your OS drive and click on OK to continue.
