When exporting all Data as Zotero RDF with files included, it can take some time. However, Zoteros loading bar does not work to tell me when the export is complete.
Note that, if you're not creating annotations, you can uncheck "Include Annotations" to greatly speed up file copying. There's also a bug in the current version where files without annotations — often the vast majority of files — will be reprocessed unnecessarily, slowing down file exports. That'll be fixed in the next version.
