Bug, calibre adding .htm ebooks as ZIP ?

carpii · 02-27-2010, 08:47 AM

I was adding some books to my library today, and noticed that quite a few of them were being added to the library as ZIP format.

After a big more investigation, it turns out that all of these files, were .htm files. I opened them to check the contents, to make sure they werent actually zipfiles with .htm extensions, but they werent.

If I tried to 'View' the ebooks, it opened my file manager and showed the file (as if it was a ZIP i guess).

But if I chose to convert it to EPUB, it worked fine.

Is this a known problem?

Putting HTML into a ZIP archive is by design. Calibre treats formats as single files. Since HTML can have accompanying other HTML, CSS, and images it is all put into a ZIP archive.

Not a problem. HTML encoded files can contain many supporting files. A ZIP is a great container to keep related pieces together.
In my case, My Astak PEz can read ZIPed HTML files directly, so no problem here.

Ok thanks guys. It makes sense

I was just a bit baffled at the time, because I was having problems and thought it was related to it being treated as a ZIP
