Why Storage Sense Only Works on the C Drive

This page explains the common confusion around Storage Sense and why it mainly targets the Windows system drive instead of acting like a full multi-drive cleanup manager.

Start with the answer

Answer the actual question first

This page starts with the direct answer because the search intent is explanatory, not command-first. Read the timing or limitation first, then use the detailed notes underneath if you still need the how-to.

Storage Sense mainly focuses on the Windows system drive, which is usually C:. That is normal behavior. If you want to clean D: or another drive, you usually need File Explorer, Disk Cleanup, or manual cleanup instead of expecting the same Storage Sense automation there.

  1. Storage Sense is designed around the drive where Windows is installed, so its strongest cleanup features usually target C:.
  2. That is why you can see good Storage Sense results on C: but almost no equivalent automatic cleanup on D: or other drives.
  3. This does not always mean Storage Sense is broken. It usually means the feature is behaving like a system-drive cleanup tool instead of a full multi-drive manager.
  4. For other drives, use File Explorer, Disk Cleanup, app uninstall checks, or manual review of large folders.
  5. Treat Storage Sense as one part of cleanup, not the only cleanup tool for every drive on the PC.
