Problem with export to single file.

Hey i noticed a problem with exporting to a single file. I don't want all the .tbn and .nfo to be in the same folder as the movies/series, so i want to export it using single file, and this has worked in the past to saves all the movie stuff in one folder and all the tv shows in one folder. But when i run the export now all the folders are empty and the only file created is the .xml. I have no idea why this is happening. The actors,movies and tvshows used to be filled with .nfo and .tbn files. Anyone know why this is happening?
