Compare a folder of Images to a CSV file in Powershell - powershell

Question

Okay so we are setting up a card access system that looks at the Active Directory Users thumbnailPhoto attribute. I am creating an audit system that exports the Users and compares them with the JPG images. If the image exists but there isn't a correlating user, it moves the image into an archive to be reviewed. The goal is to remove old employee photos into a folder incase of later hire. I can't get the image to move into another folder if it matches a name in the CSV. Here is the entire code:
<#Write Users to a CSV File #>
$adUsers = get-aduser -filter * -properties displayname | select displayname | export-csv -path PATHWAY.CSV -notypeinformation -encoding unicode
$keepImages = #()
$removeImages = #()
[System.Collections.ArrayList]$arrA = (Get-Childitem -Filter * -path PATHWAY).Basename
[System.Collections.ArrayList]$arrB = Get-Content PATHWAY.CSV
foreach ($itemA in $arrA) {
if ($arrB -ne $itemA) {
$arrB.Remove($itemA)
$removeImages += $itemA }}
$removeImages |out-file -FilePath PATH.csv
<# PUT THE FILES INTO AN ARCHIVE #>
--Cant get it to move here, note I am brand new to Powershell, its not like python at all--

You can try this. I have added inline comments to hopefully explain how it works:
$ImagesFolder = 'D:\UserImages'
$OldUserImages = 'D:\UserImages\OldUsers'
# test if the path to move old images exists and if not create it
if (!(Test-Path -Path $OldUserImages -PathType Container)) {
$null = New-Item -Path $OldUserImages -ItemType Directory
}
# get a list of ADUser display names
$adUsers = Get-ADUser -Filter * -Properties DisplayName | Select-Object -ExpandProperty DisplayName
# get an array of FileInfo objects of the user images currently in the $ImagesFolder.
# filter out only those that do not have a basename that correlates to any of the users DisplayName
# and move these to the $OldUserImages folder.
# Tip: if for instance all are of type JPG, add -Filter '*.jpg' to the Get-ChildItem cmdlet.
Get-ChildItem -Path $ImagesFolder -File |
Where-Object { $adUsers -notcontains $_.BaseName } |
Move-Item -Destination $OldUserImages -Force
If you want to keep track of the images you have moved, you can extend the above like:
$moved = Get-ChildItem -Path $ImagesFolder -File |
Where-Object { $adUsers -notcontains $_.BaseName } |
ForEach-Object {
$file = $_.FullName
$_ | Move-Item -Destination $OldUserImages -Force
[PsCustomObject]#{
'File' = $file
'MovedTo' = $OldUserImages
}
}
# show result on screen
$moved | Format-Table -AutoSize
# write to CSV file
$out = '{0:yyyy-MM-dd}_MovedImages.csv' -f (Get-Date)
$moved | Export-Csv -Path (Join-Path -Path $ImagesFolder -ChildPath $out) -NoTypeInformation
