  • System files: you can’t delete these files. The system file is necessary to run your Windows properly and can’t work without them.
  • Virtual Memory: In simple words, Windows creates and use a file on your computer as virtual memory when running out of physical memory. You can either let the system manage this file size or set a custom size for this file or even disable. If virtual memory file is taking lots of space then learn more how to manage Windows 10 virtual memory to save storage on your hard drive.
  • Hibernate: If the Windows Hibernate feature is turned on this will create a Hiberfil.sys file on the system drive. Did you ever Hibernate your PC? If the answer is No then turn it off to save huge space, learn how to turn off Hibernate that will remove hiberfil.sys file. You can’t delete this file as you do with others, turning off the hibernation is the only way to delete this file.
  • System Restore: I wouldn’t recommend to turn this feature off. This feature saves a copy of required system files whenever you want to restore previous stat after updating. If you think your Windows is stable and you don’t need to go back anytime then click the Manage system restore button and then configure the drive to delete the restore points.

TIP: The Hibernating, Virtual memory paging and restore system files are hidden by default. You can’t see them until you turn on the settings to show the hidden system files of Windows.
