Deleting temporary files in Windows 10 using Command Prompt (CMD) is a straightforward process that can help improve your computer’s performance. By following a few simple steps, you can clear out unnecessary files and free up space on your hard drive.
Deleting Temporary Files in Windows 10 Using CMD
In this guide, we will walk through the steps to delete temporary files in Windows 10 using Command Prompt. These steps will help you clean up your system and potentially speed up your computer.
Step 1: Open Command Prompt as Administrator
To start, 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: Enter the Command to Access the Temp Folder
Next, you’ll need to navigate to the temporary files folder.
Type cd %temp%
and press Enter. This command takes you directly to the Temp folder, where most of the temporary files are stored.
Step 3: Delete All Files in the Temp Folder
Now it’s time to delete the files.
Type del *.* /s /q
and press Enter. The del
command deletes files, while the *.*
specifies all files. The /s
parameter includes all subdirectories, and the /q
parameter runs the command in quiet mode, meaning you won’t be prompted to confirm each deletion.
Step 4: Confirm the File Deletion
Once you execute the delete command, you’ll see a series of file paths flash on the screen as the files are being deleted.
At this point, you have successfully removed the temporary files. Your Temp folder should now be empty.
Step 5: Close Command Prompt
Finally, close the Command Prompt window.
To do this, simply type exit
and press Enter. This closes the Command Prompt and completes the process.
After you complete these steps, your computer should have more available space, and you may notice an improvement in performance.
