The formats behind the drop zone
FB2 (FictionBook) is a single-XML format popular in the Russian-language book world — one file holding both the text and its description. CBZ is a ZIP of page images, built for comics. On the Kindle side: KF8 and AZW3 are two names for the same format (Kindle Format 8), while KFX is Amazon's newer engine with enhanced typesetting. DRM-protected books bought from a store will not open.
EPUB reflows on any screen; FB2 / CBZ are simpler containers; AZW3 / KF8 / KFX are Kindle-native. To edit an EPUB's text or metadata use the EPUB Viewer / Editor; for comics with double-page spreads use the CBZ/CBR Reader.
