Step 1:
Adding folders that contain pictures
You can add folders in two ways: Drag and drop them from their original location right into the PhotoSorts window, or browse for them from within the program by clicking on the Add folder button.
That will open a standard Browse For Folders dialog in which you can choose a folder. Clicking on the OK button will add it to the list.
When you are finished adding folders, click on the button titled Next and wait a few moments for the program to finish sorting out your pictures.
