Not currently. When Zotfile was originally written, there was no analogous free library like pdf.js for reading ePub. That’s changed, but the Zotfile developer is very active with his academic job and hasn’t had time to add major new features such as support for other file types in extraction.
+ 1 to EPUB annotation extraction and in-app reader. I know it's not a small ask, but it would make the app much more accessible, and allow users to read comfortably on smaller devices.
It seems that the reader for digital formats (mostly epub probably, based on the feedback) is much requested, apart from the extraction of annotations.
Any further info on this? Would be helpful to be able to get epub annotations into Zotero.
Seconded. An e-reader native to Zotero would be nice. Not being able to easily work with epubs is adding an extra bit of difficulty to my workflow.
I just want to link the (longer) discussion / requests: https://forums.zotero.org/discussion/comment/404730
