Want to loop through the Home directory and find a folder named tempDocuments. The physical folder structure is like D:\Home\username1\TempDocuments, D:\Home\username2\TempDocuments, D:\Home\username3\TempDocuments.  Need to loop through each users TempDocuments and delete folders older than x days.  I have a script to delete files but cannot figure out how to create a variable and store the username then evaluate the path?

Try This ( i use Powershell 3.0)

$HomeTempFolders = Get-ChildItem -Path D:\home -Recurse -Directory | Where-Object {(Split-Path $_ -leaf) -eq "TempDocuments"} | Select-Object -ExpandProperty Fullname

This code Remove all Folders that older 10 days (lastwritetime) if you remove the whatif Parameter.

$HomeTempFolders = Get-ChildItem -Path D:\home -Recurse -Directory | Where-Object {(Split-Path $_ -leaf) -eq "TempDocuments"} | Select-Object -ExpandProperty Fullname
foreach ($Folder in $HomeTempFolders) {
    Get-ChildItem -Path $Folder -Recurse -Directory | Where-Object {$_.LastWriteTime -lt (Get-Date).AddDays(-10)} | Remove-Item -Force -WhatIf 
}

!!!
The script does what you want! But remember.
It delete all Folders older than 10 days, independed of whether there are newer files contains in the folder!
