Tag Tinker's unique spreadsheet-like design maximizes the methods available for editing tags, while placing tag fields in full view and making them individually editable. Tags are made available to a wide range of auto-editing tools and features that are as close as your mouse. Custom combinations of whole tags or tag fields are easily selected to have the same automated editing function applied to all of them at one time.

Tag Tinker supports the renaming of MP3 and WMA files based upon the tag data they contain, or can create the tag data itself by extracting it from file names they already have. The file renaming "engine" is highly customizable with a straightforward interface allowing favorite formats to be created quickly and saved for later reuse. All renaming formats are made instantly available via popup menu for quick application against any combination of files. File name changes can be previewed before they are applied, and undo's are provided for both rename previews and for file name changes. Selected files or multiple folders of files can be renamed to a favorite format in just a matter of seconds.
