Match the Topic to the Question
You do not need to review every part of a drive. Start with the type of information you are trying to understand, then move to a related topic only when the evidence points there.
“Why is available space lower?”
Begin with Disk Space Analysis for the drive-level view, then use Storage Usage Monitoring if you need to compare changes over time.
Start with drive usage“Which location is large?”
Use Folder Size Analysis to follow a hierarchy. Large File Identification becomes useful when a specific personal folder deserves a closer look.
Start with folders“How should I manage these files?”
Use Duplicate File Guidance to verify possible matches and File Organization Training to create clearer permanent homes.
Start with organizationTwo complementary views
Categories Explain Type; Folders Explain Location
Windows Storage settings group data by purpose, while File Explorer follows paths. Neither view replaces the other. Learning to move between them is one of the most useful storage-analysis skills.
