Sort by filename numbers

If there are 1, 2, 3...19, 20 files, the serial number is the file name. When sorting by file name, the order is shuffled into 1, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 2, 20, 3, 4, 5, 6, 7, 8, 9 . What should I do to get these 20 files in order. ::

Numeric order filename sorting should do that (although it is on by default, so you should be seeing it already unless you've turned it off):

Thank you for saving me, I was looking in the general options of the program before. It’s in the folder options!!! ::
