Get Folder Size from Windows Command Line

Question

Is it possible in Windows to get a folder\'s size from the command line without using any 3rd party tool?

I want the same result as you would get when right clicking

Answer 1

Try:

SET FOLDERSIZE=0
FOR /F "tokens=3" %A IN ('DIR "C:\Program Files" /a /-c /s ^| FINDSTR /C:" bytes" ^| FINDSTR /V /C:" bytes free"') DO SET FOLDERSIZE=%A

Change C:\Program Files to whatever folder you want and change %A to %%A if using in a batch file

It returns the size of the whole folder, including subfolders and hidden and system files, and works with folders over 2GB

It does write to the screen, so you'll have to use an interim file if you don't want that.
