Pixort

Pixort is a nicely designed application that will let you compare, review, arrange, and organize your photo collection.

It's not just another application to view images: it was developed mainly for amateur and professional photographers working with a large volume of files that need to be organized and edited.

All you need to do is select the folder where the files are located and then select 'Scan'. The software will find all the existing photos and, if available, even show you info related to the image's exposure.

Once you select the images you want to organize, you can specify the destination folder, set up new categories, and include the same file in more than one folder.
