For some strange reason, the standard Photos App that came with my Surface Pro 3 does not display images according to file name. So even thought my files have names that are in sequential (picture_001, picture_002, etc.), the Photos app does not display them in that order. When I look in the folder containing the images with windows explorer I can see that all the files are there and in sequential order according to file name. But the Photos app does not display them in the correct order. I still haven't figured out what ordering it uses. It happens even when all files are the same file type. I tried removing all properties, but that didn't work either. Please help--this seems like such foolish behavior, I wonder if this is a bug...?
