If your Windows PC runs low on storage space, clean out the junk using these fast Command Prompt utilities.
Keeping your computer free from clutter can help improve performance and free up tons of storage space. Windows comes with several built-in system cleanup utilities, such as the Disk Cleanup tool. However, one lesser-known way to clean your computer is via the Command Prompt.
Here are a few ways to clean up a slow Windows computer using Command Prompt.
The Disk Cleanup tool in Windows 10 makes it fairly easy to clean up your computer. If any unwanted files remain, you can remove them manually. For example, clearing your temp folder. You can speed up this process with the help of commands to access the Disk Cleanup tool.
How to Use the Disk Cleanup Utility via Command Prompt
Disk Cleanup is a built-in Windows utility to help you free up space on your computer’s hard drive. It can clean up downloads, temporary internet files, recycle bins, and even system files.
You can use the Command Prompt to launch Disk Cleanup and perform automated cleanup tasks directly. Here is how to use the tool and supported command-line switches.
Basic File Deletion
You can use the cleanmgr command to launch the Disk Cleanup tool using Command Prompt. To use it:
Open Command Prompt with admin privileges by typing cmd in the search box, right-click on the command prompt and click on the run asadministrator. Type cleanmgr, and hit Enter.
In the Drive Selection window, select the drive you want to clean up and click OK.
Next, in the Disk Cleanup window, select all the files you want to delete and click OK. If you run cleanmgr with admin privileges, you will find more options to clean in the disk clean-up section.
Finally, click on Delete Files to confirm the action.
Cleanmgr /sageset
Executing this command skips the drive selection step and shows the Disk Cleanup settings window. From here, you can select the files to delete.
Delete Files Automatically
If you would rather let the Disk Cleanup utility decide what files to delete, use the command cleanmgr /sagerun. Upon execution, it will scan your drives and delete junk files from your system.
The low disk switch is useful if you are running low on storage space on your hard disk. When executed, it automatically checks all the file categories by default.
When executed, Disk Cleanup will open with all junk file categories selected from the D: drive.
To delete all junk files quickly, without the user prompt, use the following command instead: where d is the letter of the drive which is low on storage.
The Disk Cleanup tool cleans temporary files that are older than seven days. But if you have to clean the temp folder frequently, you can do it manually or use the Command Prompt.
You can delete the temp file manually (Ctrl + A > Delete) from File Explorer or use the following command to delete temp files:
Command Prompt will automatically skip any file that is currently in use, but it will delete the rest.
How to Delete Prefetch Files Using Command Prompt
Prefetch files are temporary files created when an application is run on your Windows system. These files contain information that is used to optimize the execution of programs.
Similar to other temporary files, prefetch files often don’t take up much space on your hard drive. However, if you need to delete prefetch files frequently, you can use the Command Prompt to clean up these files on your system.
To delete prefetch files using Command Prompt:
Open Command Prompt as administrator
To delete the prefetch files, use the following command and hit enter:
Keep Your Computer Clean From Junk Files Using Command Prompt
You can use the Command Prompt to perform various advanced actions, including removing junk files from your computer. While you can use the GUI-based Disk Cleanup tool, Command Prompt makes it easy to clean up individual category files and wipe clean disks.
