Listing a directory sub directories and size

I'm having issues with this snippet of code to find the folders in a directory and list with sizes but I keep running into a error

$Directory = Read-Host "Enter your directory"

$colItems = (Get-ChildItem $Directory |  {$_.Attributes -match 'Directory'} |Measure-Object -Property Length -Sum  )

After adding bit after | to show the sizes I started getting errors.

You can use the Scripting.FileSystemObject COM object for simplicity.

$Directory = Read-Host "Enter your directory"

$fso = New-Object -ComObject Scripting.FileSystemObject

Get-ChildItem -Path $Directory | ? { $_.PSIsContainer } | % { $fso.GetFolder($_.FullName).size/1kb }

Try this

$Folders = Get-ChildItem $Directory | Where-Object {$_.Attributes -eq 'Directory'}
foreach ($Folder in $Folders)
    {
        $FolderSize = Get-ChildItem $Folder.Fullname -recurse | Measure-Object -property length -sum
        $Folder.FullName + " -- " + "{0:N2}" -f ($FolderSize.sum / 1MB) + " MB"
    }

-Recurse Parameter makes sure that apart from getting System.IO.DirectoryInfo you are also getting System.IO.FileInfo objects which contain Length property.

I would also suggest that instead using

$Folders = Get-ChildItem $Directory | Where-Object {$_.Attributes -eq 'Directory'}

You can use:

$Folders = Get-ChildItem $Directory | Where-Object {$_.PSIsContainer -eq $True}

This property will be available for other providers (registry, cert store, etc.) as well.

Directory objects (objects of type DirectoryInfo) don't have a length property, which is why you are getting errors. In order to get the space taken up by directories in powershell you'll have to recursively search through all the subdirectories and adding up the length of all the files that they contain. Fortunately there are several sources available to show you how to do this. Here's one.
