How To View Folder Size In Windows 8.1 Explorer

Windows 8.1, just like its predecessors, doesn’t show size of folders in Windows Explorer (File Explorer) by default. That is, when you open up a folder containing several files and folders, Windows Explorer shows only the size of files and not folders in Details view.

In order to view the size of a folder in Windows Explorer, one needs to either hover mouse cursor on the folder, or select the folder, right-click on it, and then click Properties (one can quickly open properties by using Alt + Enter hotkey).

Folder Size is a small but very useful shell extension designed to show folder size in Windows Explorer. While this tool shows the folder size right in Windows XP’s Explorer, it doesn’t show size of folders inside the Explorer when you’re using it in Vista, Windows 7, and Windows 8.1, and instead, whenever you open up a folder containing sub folders, it shows a pop-up window with size of all folders.

    This does NOT add a column, but has a separate pop out window with a duplicate list of folders with sizes. BUT you cannot delete, move, copy, rename, or do ANYTHING… so it is helpful to a degree, but would be a LOT better if it was just a column added.
