It’s a no-nonsense software that integrates itself with the File Explorer in Windows 10. It registers itself as service, and keep a monitor on size changes. As soon as you open any folder, it will display a floating pop-up window that will have a list of all the files and folders along with folder size.

Windows don’t display folder size in File Explorer, but only displays for files. Thats annoying, and this software can fix it. Thats how it used to look in an earlier version of Windows XP and was perfectly integrated. However, Post Windows Vista things changed, and now in Windows 10, it displays as a floating window.

Windows does show file size but its not very convenient.  You can enable it by following these steps

Display Folder Size in Tooltip

  •  Go to File Explorer Options > Switch to “View” tab
  • Check the box which says show folder size in a tooltip
  • Apply and exit.

Next, hover your mouse over any folder, and it will display a tooltip with a yellow background. It will have the folder size listed. I wish Windows has this implemented, and its nothing that cannot be done. Its already there, all they need is to convert it into a column.
