[Travesso]

The rational explanation is a quirk with windows explorer actually. When u select a group of files in any view type and copy them or open them, (even in list or details mode) windows will always take the last selected file and open it first, then the remaining files in the order u selected them. To test this, try opening multiple files in any program (such as word or excel, autocad or whatever), then go to the "Window" menu and look at the order of the window list. The only way I found to get around this is to select the files in reverse order (bottom up). Admin is correct, the Mp4 player plays files in the order they were copied. Just keep in mind you might need to select the files from the bottom up in explorer.
