Remove Read Only Item Flag

I recently had an issue where I needed to update the Read Only Item Property on a large set of files. 

Below is a script that will process all files under 'C:\BACKUPFILES' and set the Item Property 'Read Only' to false on all files. 

$FolderPath = 'C:\BACKUPFILES'
$setRoAttributeTo = $false
$Items = Get-ChildItem -Path $folderPath -Recurse
Foreach ($File in $Items) {

 IF ($file.Attributes -like '*ReadOnly*'){
Write-Host $file.FullName
Write-Host "File Read Only" -BackgroundColor DarkRed
  Set-ItemProperty $File.FullName -Name IsReadOnly -Value $setRoAttributeTo
