You will be able to sort your images in Browse by using the sort drop-down menu in the lower left-hand corner of the program window. This is shown in the screenshot below:
Simply click to expand the sort menu and choose how you would like the folder to be sorted. The Sort By pop-up adjusts sort order based on standard selection criteria, such as file name, date captured and more. (You can also create your own custom sort order in ON1 Photo RAW 2018.)
Please note, this will only work within the folder that is open within the Browse preview window.
