Attachment formats (other than PDF)


I’m wondering if its possible to attach other formats and then download them later in the original format. I’m finding that currently its downloading the file in zip and then within the zip I get cpgz when I open the zip. I have a bunch of .epub format that I do not need to read in paperpile, however it would be handy to store them in paperpile so I don’t have to find them later (and identify where I stored them). Additionally I tried uploading a jpg just to see if that works and I have the same problem…no luck there either. I also tried changing the filename to .pdf for fun and now I can’t download, rename and then reopen…
