Simply Sorted Snaps scans your default picture directories (and you can specify others) and allows you to apply 'filters' to them to create a new structure layed out how you want.
You can then apply your changes by one of two methods: copy and move. You can make a clone of your picture directory that is sorted and save it elsewhere, or you can move the pictures to a new directory.
If you don't like your changes, no problem! Simply Sorted Snaps allows you to revert them back to the way they were before.
Try it for yourself and manage your photos better than you ever have!
