nice find TaKir, those formats are new
The comparison page here proves it:
https://www.mobileread.com/eink/
However I went to the V2 page at:
http://www.jinke.com.cn/compagesql/E...tail.asp?id=20
and it has this list of supported files
PDF Viewer, WOLF Viewer(WOLF File Format:convert from txt,htm,DOC ,PDF,Excel,PPT,Images,mp3 ets),HTML Viewer,TXT Viewer
perhaps they havent updated the product page yet
