One of the biggest effects caused by dropping hard drive prices and faster internet speeds is that we have more files on our computers. You may probably just randomly copied or downloaded tons of files to couple of default folders like "downloads". Then the question is how to sort them all? Digital Janitor presents an easy solution for this problem:

You select the folder you want to sort, then define the file types and the destination folder for these file types, and all there is left for you to do is clicking the “Auto-Sort” button, the program moves all the specified file types to your desired destination folder. Like all mp3 files to /music folder, all doc files to /documents folder and etc.
