Child directory sizes and owners - powershell

Question

I'm trying to write a PowerShell script retrieving the directory size and owner on my Windows file systems. I've got two separate scripts that work independently, but I don’t know how to put them together as a single script file.
Directory Name and Size:
$startFolder = "C:\Test”
$colItems = (Get-ChildItem $startFolder | Where-Object {$_.PSIsContainer -eq $True} | Sort-Object)
foreach ($i in $colItems)
{
$subFolderItems = (Get-ChildItem $i.FullName | Measure-Object -property length -sum)
$i.FullName + " -- " + "{0:N2}" -f ($subFolderItems.sum / 1MB) + " MB"
}
Directory owner:
Get-ACL C:\Test
I'd like for the script to output to a CSV file.

Answer 1

So something along the lines of this then?
$start = "c:\temp"
$output = "C:\temp\output.csv"
Get-ChildItem $start | Where-Object{$_.PSIsContainer} | ForEach-Object{
$singleFolder = $_.FullName
$folderSize = Get-ChildItem $singleFolder -Recurse -Force | Where-Object{!$_.PSIsContainer} | Measure-Object -Property length -sum | Select-Object -ExpandProperty Sum
$folderSize = [math]::round($folderSize/1MB, 2)
$owner = Get-Acl $singleFolder | Select-Object -ExpandProperty Owner
$_ | Add-Member -MemberType NoteProperty -Name FolderSize -Value $folderSize -PassThru |
Add-Member -MemberType NoteProperty -Name Owner -Value $owner -PassThru
} | Select-Object FullName,FolderSize,Owner | Export-Csv $output -NoTypeInformation
Needed to add some extra logic in length calculation to keep folders out of the mix > Where-Object{!$_.PSIsContainer}. This should work with PowerShell 2.0 just fine.
It loops through each folder in the root of $start and for each $singleFolder calculates the size of the contents and folder owner.
The variables are then added to object through pipeline with Add-Member as the properties FolderSize and Owner. The final Select-Object is used to isolate the properties we want for the output file.
Sample
FullName FolderSize Owner
-------- ---------- -----
C:\temp\37 Place i.Bay domain\guy
C:\temp\adoc42 1103186357 domain\guy
C:\temp\Adoc72 958330505 domain\guy
Notice the empty folder. That output is sent to Export-CSV in the file $output
