How to Make File Explorer Show Folder Sizes in Windows

Goal / What the tutorial does

• Shows how to make Windows File Explorer (Details view) display folder sizes next to folders.
• Without the mod:
  • Folders show no sizes by default.
  • You’d otherwise need to hover or use Right-click → Properties to see sizes.

Tool used (Windows “mod” system)

• Uses a free mod manager app referred to in the tutorial as Winaero Tweaker? (the subtitles show something like “wind Haw”; context suggests a Winhawk/WinHawk-style mod system).
• Workflow described:
  1. Install the free mod manager.
  2. Open the app’s Explore section to browse/search suggested mods.
  3. Find the mod “Better File Sizes in Explorer Details”.
  4. Click Details → Install.
  5. Enable/disable the mod using the app’s controls.

Key product feature: “Better File Sizes in Explorer Details”

• Adds folder size calculation so File Explorer can show sizes in Details view.
• Sorting behavior:
  • Sorting by size can place folders at the top or bottom.
  • File Explorer still groups folders together, so folders won’t intermix with files by size.

Important settings (performance + usage options)

The mod includes a “calculate folder sizes” option with modes:

• Disabled
• Always enabled
• Enabled while holding the Shift key (on-demand)

Performance note

• Always enabled may cause slowdowns, because File Explorer must calculate folder sizes each time—especially when there are many folders.
• Shift-key mode reduces overhead by calculating sizes only while the user holds Shift.

User actions shown in the tutorial

• After changing settings:
  • Click Save settings
  • Then refresh File Explorer to apply the changes.
• In Shift-key mode:
  • Hold Shift + refresh to show folder sizes
  • Release Shift + refresh to hide them again
