You want to remove everything excepting the opening bracket `(` `CD` Space 4 digits the closing bracket `)` ? Or does the part inside the brackets varies? ---

What do you mean? The more to the point your question is, the higher the quality of the answer probably is. So you want to import data from the folder? Such a case is described in the documentation: > **[Import Tags from File and Folder Names – Mp3tag Documentation](https://docs.mp3tag.de/converters/import-tags-from-filenames/#import-parts-of-the-folder-structure-to-the-tag)** > > Documentation on Filename to Tag, a converter to import tags from file and folder names. Mp3tag is the universal Tag Editor. ---
