maybe I am not following you .
Kovidgoyal , I drag my .RAR archive into calibre, it detects the name and the author of the file.
When i right click and say view file , nothing happens.
Sending the same file to my device , sends the .RAR file and not any epub.
It's treating the ebook as an archive now.
How do I add the file to calibre , that all the .ncx , .opf and html are utilised ?
