Possibly a basic question, but I'm using Calibre and I want to keep the EPUB files I import unchanged. I've noticed that as long as I'm just modifying the metadata and the cover, the EPUB file remains unchanged. However, when I open it in the eBook editor without saving or making any changes, just by opening some XML of the eBook and then closing the edit window, the EPUB file in the library appears to be altered with the cover inside overwritten by the external cover. Is there a way to prevent this? Also, even though the "save_original_file" options are set to "true," no .original_epub file is created either during import or after editing the cover or metadata.
