If you're running low on disk space, it's important to identify large files that you no longer need and delete them. Windows 10 provides an easy way to find large files using File Explorer.

Enable Show hidden files and folders 

• Open the Start Menu and search for Show hidden and click on Show hidden files and folders.

• When the dialog box opens, click on the View tab at the top. You’ll see various File Explorer options that you can modify.
• Find the option that says Show hidden files, folders, and drives and put a checkmark in it. Then click on the OK button to save your changes.
  
  
• Double-click on This PC on your desktop to launch File Explorer. When the utility launches, click on the search box given at the top-right corner.
• A new menu item will be added to the top of your screen. Click on the newly added item that says Search to view further options.
• Select the Size option and then select an appropriate option from the list. It’ll let you find large files available on your PC.
