If the specific extensions you are looking for are: .csv first and then .cnf
You can use this code.

Change the variable $ChkDir to the directory you want to check.

code:
$ChkDir = "C:\Temp\"
 
$Csv_File = Dir($ChkDir + "*.csv")
While $Csv_File <> ""
	$Cnf_File = $ChkDir + SubStr($Csv_File, 1, Len($Csv_File) - 4) + ".cnf"
	If Exist($Cnf_File)
		Del $Cnf_File
		Del $ChkDir + $Csv_File
	EndIf
	$Csv_File = Dir()
Loop
