Is the page file consuming storage?

The page file (pagefile.sys) is used for virtual memory and typically equals your RAM size. It is essential for Windows operation but can be configured.

Is the page file consuming storage? explained

  • Temporary installation files
  • Browser caches and downloads
  • Windows Update cache and remnants
  • Hidden system folders
  • Recycle Bin contents
  • Application data in AppData
