eBook viewer

Any plans to support viewing of eBook formats for the Directory Opus viewer.

Here is same book in Total Commander viewer

This is the epub in Directory Opus when it is viewed inside a zip folder

Here are the contents of the total commander plugin folder that deals with viewing eBooks.

Any eBook preview handler that works in File Explorer should also work in Opus. There's also a native viewer plugin API if anyone wants to write an Opus-specific one.

can you point me to any eBook preview handlers that will work in dopus ?

I've never used eBooks myself, and do not have any, so I don't know which to recommend. Google finds several results that look worth a try.

eBooks are a thing now, here to stay. I'm not up to writing a preview handler and would certainly pay extra bucks for this feature, say for version 13 :grinning:
I did look at the sumatra page and apparently it's open source, does all these formats - Perhaps you or some other capable programmer could have a look ?

Sumatra already has a preview handler. It's an option during installation.

How do i set it up in dopus ?

The same as in File Explorer. Select the option in the installer.

Whether it views only PDFs or eBooks as well, I don't know.

If you need help with Sumatra, please ask on the support site for Sumatra.

yes its for pdfs only, can view them in windows explorer when item is checked. Does not do epubs, mobi, etc.

.epubs are just zip files - add the extension to Opus prefs and you can double click them to view the contents, then preview the .html files. Not the same but good enough for a quick preview surely.
