So, I have all these articles that I have annotated/highlighted/etc. and I know the option to export a pdf with all of these, but all I really want to do is send someone the original unedited file. Whenever I use the export function, there is a good bit of quality loss, and the file is saved as a picture (can no longer highlight text).

Does anyone know how to do this? I know the library is just a database, so the original file has to be somewhere, right?
