Method 4 - Delete junk files in Windows 11 by checking the Downloads folder
Typically, everything you download from a web browser goes to the Downloads folder, which tends to grow large over time. Therefore, here's how to delete junk files in Windows 11 by removing unnecessary files in the Downloads folder:
- Double-click “This PC” on the “Desktop.” Alternatively, press the “Windows+E” keys to open “File Explorer.”
- Choose “Downloads” from the left side panel.
- View the files inside and delete those you don't need.
Method 5 - Delete junk files in Windows 11 by removing installers
An installer, aka an installation package, often becomes useless after the software/application/program is successfully installed. Some of them may be in the Downloads folder. If not, follow the steps below to search for the installer file in Windows 11:
- Double-click “This PC” on the “Desktop.” Alternatively, press the “Windows+E” keys to open “File Explorer” and choose “This PC” from the left side panel.
- Tap on the search box on the right, input *.exe, *setup*.exe, or *installer*.exe.
- After scanning is finished, identify the apps' installers and delete them if you want to.
Method 6 - Delete junk files in Windows 11 by disabling hibernation mode
Hibernation mode in Windows allows you to shut down your Windows PC without losing your work. When you put your computer into hibernation, Windows saves all open files, apps, programs, and settings into a file called hiberfil.sys on HDD/SSD.
When you turn the Windows PC back on, the hiberfil.sys allows you to restore the state to exactly where you left off without needing to reopen apps, programs, or files; they will be just as they were before hibernation.
Few Windows users know that the hiberfil.sys file is likely to be large (several GBs), and it will not be automatically removed. Disabling hibernation mode can remove the old hiberfil.sys file.
Here's how to delete junk files in Windows 11 by disabling hibernation mode:
- Open "Control Panel" on Windows 11.
- Switch to the "Large icons" view method.
- Tap on "Power Options."
- Click "Choose what the power buttons do" from the left side panel.
- Click "Change settings that are currently unavailable."
- Uncheck "Hibernate" and tap on "Save changes." This disables hibernation mode and deletes the hiberfile.sys file.
Alternatively, you can disable hibernation mode through the Command Prompt:
- Press the "Windows+S" keys to open the Windows search box.
- Input "cmd" and choose "Run as administrator."
- When the command window appears, input "powercfg /hibernate off" and hit the "Enter" key on your keyboard.
Method 7 - Delete junk files in Windows 11 by removing Windows update files
Windows Update service stores many temporary update files, such as installation files and update history, to the SoftwareDistribution folder in the system drive, which can occupy a lot of space.
Deleting the files in the SoftwareDistribution folder can free up much disk space, but it won't damage your current updates or system functionality. However, it will cause Windows Update to recreate update files the next time it checks for updates, and the update check could take a little bit longer than before.
Here's how to delete Windows update files:
- Open "Command Prompt" as an administrator through the Windows search box.
- Input “net stop wuauserv”, “net stop bits” into the command window, and hit the "Enter" key after each to stop Windows update service.
- Double-click "This PC" to open "File Explorer."
- Navigate to C:\Windows\SoftwareDistribution
- Select all the files and subfolders, and then right-click on them to delete.
- Run the Command Prompt as an administrator again.
- Input and execute “net start wuauserv” and “net start bits” commands one by one to restart the Windows update service.
Method 8 - Delete junk files in Windows 11 by disabling system protection
The System Restore feature in Windows relies on System Protection to create restore points that can help revert your system to a previous working state, which often comes into play when Windows acts up.
However, system restore points can pile up and take up much space. Disabling System Protection can help delete these restore points, but also means you won't be able to perform a system restore.
Here's how to delete junk files in Windows 11 by disabling system protection:
- Open the Windows search box, type "Create a restore point", and click the result to open.
- Select a hard drive from the box and tap on the "Configure" button.
- Choose "Turn off system protection."
- Click "Apply" and "OK" to save changes.
