I moved it to the root (of course Calibre changed all the paths inside files) - the same problem.
I don't think the problem is with the relative paths as I said if the files are placed in another directory along with the opf file then there is no problem with Calibre viewer.
container.xml points with the full path to opf file and from there on there should be no matter if directory is named meta-inf or whatever.
The paths are indeed relatively specified in opf file like this and they are in the opf's directory:
Code:
<item href="titlepage.xhtml" id="titlepage" media-type="application/xhtml+xml"/>
<item href="Maikite_-_Teodora_Dimova_-_4eti.me_split_000.htm" id="html10" media-type="application/xhtml+xml"/>
<item href="Maikite_-_Teodora_Dimova_-_4eti.me_split_001.htm" id="html9" media-type="application/xhtml+xml"/>
Every other reader that I tried opens the files with no issues. This only happens with Calibre new viewer.
E.g. Moon Reader+, AlReader, FBReader, CoolReader (desktop and mobile version) open the files correctly.
