How to batch export FB2 files in Calibre while keeping original filenames?

Hi everyone,

I need to batch re-save a large number of .fb2 files using Calibre, but I want to preserve their original filenames when saving them to disk.

I’ve noticed that Calibre uses filename templates when exporting files, but I couldn’t figure out which template would allow me to keep the current file names exactly as they are.

Is there a way to do this — maybe using {basename} (not working) or something similar in the template settings?

Any help would be greatly appreciated!

Thanks in advance.
