Filr

Filr is a compact application that allows you to quickly and easily rename, tag, and comment on files. It works a bit differently than most tagging apps: when a group of files is opened, Filr presents each one individually rather than as a group. Its great for sorting through groups of potentially unrelated files. Rename: Change the name of the file. Filr preserves the extension so you dont have to. Tag: Filr allows you to easily add and modify OpenMeta tags, so its perfect for a tag-based workflow. Comment: FIlr can show and edit the files Spotlight comments, so you can add short notes to any file. When used with a Folder Action script or a 3rd-party scripting application like Hazel, you can add a group of files to a folder and then immediately step through each one, changing its name, tags, and comment to something appropriate for the file. Its quick and seamless.
