Powershell folder size of folders without listing Subdirectories

Question

I have found several resources that use the following script to get folder sizes

$colItems = (Get-ChildItem $startFolder -recurse | Where-Object {$_.PSIsContaine         


        

Answer 1

This is something I wind up looking for repeatedly, even though I wrote myself a nice little function a while ago. So, I figured others might benefit from having it and maybe I'll even find it here, myself. hahaha

It's pretty simple to paste into your script and use. Just pass it a folder object.

I think it requires PowerShell 3 just because of the -directory flag on the Get-ChildItem command, but I'm sure it can be easily adapted, if need be.

function Get-TreeSize ($folder = $null)
{
    #Function to get recursive folder size
    $result = @()
    $folderResult = "" | Select-Object FolderPath, FolderName, SizeKB, SizeMB, SizeGB, OverThreshold

    $contents  = Get-ChildItem $folder.FullName -recurse -force -erroraction SilentlyContinue -Include * | Where-Object {$_.psiscontainer -eq $false} | Measure-Object -Property length -sum | Select-Object sum
    $sizeKB = [math]::Round($contents.sum / 1000,3)   #.ToString("#.##")
    $sizeMB = [math]::Round($contents.sum / 1000000,3)   #.ToString("#.##")
    $sizeGB = [math]::Round($contents.sum / 1000000000,3)   #.ToString("#.###")

    $folderResult.FolderPath = $folder.FullName
    $folderResult.FolderName = $folder.BaseName
    $folderResult.SizeKB = $sizeKB
    $folderresult.SizeMB = $sizeMB
    $folderresult.SizeGB = $sizeGB
    $result += $folderResult

    return $result
} 


#Use the function like this for a single directory
$topDir = get-item "C:\test"
Get-TreeSize ($topDir)

#Use the function like this for all top level folders within a direcotry
#$topDir = gci -directory "\\server\share\folder"
$topDir = Get-ChildItem -directory "C:\test"
foreach ($folderPath in $topDir) {Get-TreeSize $folderPath}
