Disk diagnostic: free space and large files

This diagnostic checks whether storage is low on space or whether certain volumes are becoming a slowdown factor.

What PowerIX checks

  • free space
  • detected volumes
  • large areas
  • Windows Update blockage risk
  • performance impact

Problems this diagnostic helps explain

Privacy and limits

  • the diagnostic works on sizes and technical paths
  • file contents are not opened

After the diagnostic

  • free space without deleting Windows
  • back up before a large cleanup
  • cross-check disk health if the drive seems fragile
