when I use an action to move a file

Which action is that? Could you show us the parameters?
Also, see the documentation:

Rename Files and Import Tags from Files

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. …

and in general: if you want to move folders, rename the folder (_DIRECTORY) , if you want to move single files, rename only the file (_FILENAME).
