Remove iislogs

Built a nice script to remove older files from IISLogs.
It has two retentionmodes. Either clear based on number of last changed files or for specific days.

	$scriptPath = $(split-path -Parent $myinvocation.MyCommand.Definition)
	Import-Module "$($scriptPath)\XssIisTools.psm1" -Force
	#$logPaths = "D:\LOGS\IIS\W3SVC2000719483","D:\LOGS\IIS\W3SVC184136160","D:\LOGS\IIS\W3SVC1417816532" #variant1 only selected folders
	$logPaths = Get-ChildItem -Path "D:\LOGS\IIS\" |where-object {$_.PSIsContainer} |select -ExpandProperty FullName #variant2 all subfolders folders in selected path
	$filetypes = "u_ex*.log" #what files to delete
	$numerOfFileToKeep = 30
	$logFileName = "LastRunLog.txt"
	$logFilePath = Join-Path -Path $scriptPath -ChildPath $logFileName
	Start-Transcript -Path $logFilePath
	foreach ($logPath in $logPaths) {
	remove-IISLogs -logPath $logpath -fileTypes $filetypes -count $numerOfFileToKeep
	}
	remove-IISLogs -logPath "D:\LOGS\ELMAH\App_Data" -fileTypes "*.xml" -retentionMode Days -count 30
	Stop-Transcript
