There is a whole chapter in the Mac documentation about how to get information from or write it to filenames, see here:

> [@Rename Files and Import Tags from Files](https://community.mp3tag.de/t/rename-files-and-import-tags-from-files/51720):

> Mp3tag provides a variety of possibilities to get tag information from parts of the filename 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 filename. 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. …

If you have a specifc problem, then give a real example.  
A general hint: if you want to modify a filename, then use the tag information and write a completely new filename. Use Convert\>Tag-Filename  
If you want to get information from a filename, use Convert\>Filename-Tag. If the filename has parts that you don't need, mask these parts with %dummy%
