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

The base concept behind all converters in Mp3tag is the format string, which describes a pattern or template of a file name.

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.
