Solved Directory sizes in explorer

I'm new here so maybe this is something discussed before

Can anyone tell me if it is possible to list directory sizes in explorer just as you would see thmem against any other file

Welcome
I use windirstat for all kinds of information. Maybe it will help you too
WinDirStat - Windows Directory Statistics

If you are willing to use a File Manager FreeCommander works quite well. It has a KB Folder Button on the Toolbar that shows the size of folder contents. It's off by default to keep the app from slowing down.

As the name implies, it's free software:

FreeCommander - freeware file manager

Here's a screen shot with the button enabled for the right hand pane:

TY for your kind words and rep. I will mark this closed.
