Hello everybody, I trying to modify a file based on items who are stored in a array. The purpose is to delete all lines in the Test-Maps.ini file where the words in the test_list.ini are NOT present but I am a littlebit stock at the moment, any ideas or help? Many thanks in advanced. Kindly Regards Koen --------------------------------------------- This is my code what I currently have: #include <GuiConstants.au3> #include <Array.au3> #include <file.au3> Dim
