Show Folder Size in Explorer: Which third-party tool?

In searching for a solution to making Windows Explorer show folder sizes, I've come across many threads here and elsewhere.

What I cannot find is which free third-party tools are most suitable for one who is somewhat technically challenged and gets confused with too many options.

I'm looking for a lightweight tool with relatively few bells and whistles that will display folder size in Windows Explorer.

I appreciate any suggestions- thank you.

Hey ixodid,
Give these a look ...
TreeSize - TreeSize Free - Quickly Scan Directory Sizes and Find Space Hogs
WizTree - Antibody Software - WizTree finds the files and folders using the most disk space on your hard drive

I may be misunderstanding your request? You want to have the folders permanently showing siz, or only for an immediate glance+

I just right click a folder and then properties - shows all.

Sorry if I wasn't clear in my original post. I want to have the folders permanently showing size.

Using Properties from the context menu is kind of a pain when I want to see the sizes of multiple folders. And waiting for the tooltip to appear is also inconvenient.

I want to be able to see the folder size displayed in the Size column just as it is for files - like in the screen shot dalchina included in post #5 above.

How about this? https://sourceforge.net/projects/foldersize/
