Comparing a CSV to a Share

Comparing a CSV to a Share

Comparing a CSV to a Share

Good Day,

We have several thousand users in our Active Directory. I have created a PS script to pull all of the users into a CSV file.

In a share we have folder for each user - about two thousand of these folders are old and need to be removed.

I would like to compare my CSV file of active users against the list of folder names in the share, listing all of the folders that are old and need to be removed.

I'm about at my wits end trying to get my script to run properly.

Any tips on a proper way to script this would be great.

Kindest Regards,


RE: Comparing a CSV to a Share

Are you still in need of assistance? I've been away for a while, but I'd be willing to help out, now, if I can.

If so, what would determine if a file was "old and need to be removed"? They don't show as a user in your AD user export?

Assumptions I'm making until I hear from you:
1. Directory names are equal to the users' SamAccountName
2. You have a SamAccountName attribute in the AD export

So, I think it would go something like this

CODE -->

$import = Import-Csv "C:\temp\user_export.csv"
$users = @()
foreach ($i in $import)
	 $users += $i.SamAccountName

#get directories$path = "c:\temp\userdirs\"
$dirs = Get-ChildItem -Path $path -Name

#find directories to remove
$removals = @()
foreach ($dir in $dirs)
	 #directory is not in the list of users
	 if (!($users -contains $dir))
		 #add dir to removal list
		 $removals += $dir
$removals | Out-file "C:\temp\remove_dirs.txt" 

If you don't need to review the list you could remove them from the script instead of exporting them. You can add something like this into the if-statement:


if (!($users -contains $dir))
	 #add dir to removal list
	 $removals += $dir
	 #remove directories
	 $dir2remove = $path+$dir
	 Remove-Item $dir2remove -Recurse -Force -Confirm:$False -EA SilentlyContinue

RE: Comparing a CSV to a Share

I see a typo in the first code block:


#get directories$path = "c:\temp\userdirs\" 

Should be:


#get directories
$path = "c:\temp\userdirs\"
