If you’re looking to clean up your Windows 10 PC and get rid of those pesky junk files, using Command Prompt (CMD) is a quick and efficient way to do it. By following a few simple steps, you can easily delete unnecessary files that are taking up valuable space on your computer. This guide will walk you through the entire process, ensuring that your system runs smoother and faster.
How to Delete Junk Files in Windows 10 Using CMD
In this section, you’ll learn how to use Command Prompt to delete junk files in Windows 10. This method is particularly useful because it allows for precise control over what files are removed, ensuring that only unwanted files are deleted.
Step 1: Open Command Prompt as Administrator
First, you need to open Command Prompt with administrative privileges.
To do this, type "cmd" in the Windows search bar, right-click on Command Prompt, and select “Run as administrator.” This ensures you have the necessary permissions to delete system files.
Step 2: Use the Cleanmgr Command
Next, you’ll use the built-in Cleanmgr command to start the cleanup process.
Type "cleanmgr /sageset:1" and hit Enter. A window will appear allowing you to select the types of files you want to delete. This step sets up a configuration that you’ll run in the next step.
Step 3: Run the Cleanup Configuration
Now you need to execute the cleanup using the configuration you set up in Step 2.
Type "cleanmgr /sagerun:1" and press Enter. This command will run the Disk Cleanup utility using the settings you specified, removing the selected junk files.
Step 4: Delete Temporary Files
To specifically delete temporary files, use a dedicated command.
Type "del /q/f/s %TEMP%*" and hit Enter. This command will delete all temporary files in the TEMP folder without asking for confirmation.
Step 5: Clear the Prefetch Folder
Lastly, clean out the Prefetch folder to further optimize your system.
Type "del C:WindowsPrefetch*.* /Q" and press Enter. This will remove all files in the Prefetch folder, which helps the system start programs faster but can get cluttered over time.
Once you complete these steps, your computer should run a little smoother and have more free space. You might not notice a dramatic change immediately, but these steps help maintain your system over the long term.
