Advanced Renamer

Advanced Renamer is a soup-to-nuts application that allows you to quickly and easily rename a whole host of files with far more customization than you'll ever find via Windows itself. Once you've fired up the app, you add the target files to the window on the right-hand side, then perform all your customizations—including mass case changes, renaming according to tags (like an image's width or height), and find/replace/move commands for individual characters within a file's preexisting name—on the left-hand side of the application.
