Powershell script fo deleting specific-files-from-sharepoint-on-premises-library error

thank you so much for your reply Matt Weston. looks simplified now.

I ran the following script:

# SET UP

Add-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue

CLS

# PULL IN THE CSV

$filelist = Import-Csv -Path "C:\temp"

foreach($file in $filelist)

{

 Write-Host "Processing $($file.File)"

# Figure out the URL of the site

 $arysiteurl = $file.File.Split('/')

 $url = ""

 for($x=0; $x -lt $arysiteurl.Length-2; $x++)

 {

 $url = $url + $arysiteurl[$x] + "/"

 }

# Get the web

 $web = Get-SPWeb $url

# Get the document based on the URL

 $file = $web.GetFile($file.File)

 $file.Delete()

}

I get the following error:
