Digital cameras are great for taking loads of pictures and discarding any of them you don't like. The problem comes when you want to keep all of them, regardless of their quality: you need a good management tool before chaos takes over your image directory.
This is when Amok Exif Sorter comes in handy. This photo organizer enables you to rename your images and image directories according to the Exif data saved with each photo. In this way you'll be able to have all of your pictures perfectly organized in folders by the date they were created, the camera they were taken with and a lot more filters.
What I really liked about Amok Exif Sorter was the wide array of available options when renaming the files. However, the program is not very user-friendly in this aspect, as there's no included documentation to explain all the possible variables – plus, the online help section is only in German. In any case, you can see a preview of the new name before applying it, which is always helpful.
Although it takes a while to explore all the renaming possibilities in Amok Exif Sorter, it's worth it. This program is a great companion for all digital camera owners.
