Mp3tag provides a variety of possibilities to get tag information from parts of the filename or rename files based on the information stored in the tag of a file.

The base concept behind all converters in Mp3tag is the so called format string, which describes a pattern (or template) of a filename or a line in a tag-list file.

A format string consists of any characters and predefined placeholders or scripting functions. Every placeholder begins with the percent sign `%`, followed by a tag field name and ends with the percent sign.  
For example, the placeholder `%album%` refers to the `Album` field.
