oh yes, the image posted was only a test with the 2014 version, your great work I still have to test, as you know the choice of masks is not simple, and it's all based on the "arc.groups", the use default of your "arc.ini" and the various options can give the right idea, but I always recommend to scan the folder to be compressed, to check and know the various file formats, and use the right chain of masks.
Already existing scanning files utility, in this forum section.
