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

Here comes a powershell code I write to list size and file count for all folders under current directory. Feel free to re-use or modify per your need.

$FolderList = Get-ChildItem -Directory
foreach ($folder in $FolderList)
{
    set-location $folder.FullName
    $size = Get-ChildItem -Recurse | Measure-Object -Sum Length
    $info = $folder.FullName + "    FileCount: " + $size.Count.ToString() + "   Size: " + [math]::Round(($size.Sum / 1GB),4).ToString() + " GB"
    write-host $info
}
