Tag editor
From Wikipedia, the free encyclopedia
A tag editor (or tagger) is a piece of software that supports editing metadata of multimedia file formats rather than the actual file content. These are mainly taggers for common audio tagging formats like ID3, APE and Vorbis comments (for example Windows Media Player and iTunes), but can also be taggers for JPEG and TIFF metadata, for example (iPhoto).
A common purpose of a tag editor is to correct and sort multimedia files, for example a music collection. This often happens in a batch processing mode so that you don't have to manually edit every file on your own.
