Automatic export for a folder tree

I've organized my music in a folder tree (one album is one folder) and I would like to create one export-file per folder with Mp3tag.
Is there a way to select in export just the root of this folder hierarchy and Mp3tag creates/updates export-files in each subfolder (for each album) automatically?

Thanks for hints!

MP3tag uses export scripts for the loaded (and selected) files.
So you would have to load and select them first.
THen it is up to the export script which information gets how exported.
See the help for export as an introduction.
