Calibre ebook-viewer.exe changes EPUB file sizes?

avid01 · 07-15-2013, 06:07 AM

I do not use Calibre as a manager, only as a converter. Note: I have the Alf/DeDRM plugin installed into the manager. But ebook-viewer.exe is a separate entity on it's own, right?

I launch ebook-viewer.exe separately to view e-books. And the file sizes of my EPUBs wihich were DRM free in the first place change. Why?

Should I keep two separate installs of Calibre on my machine, one for general use and one for Alf only and it will solve my problem?

Current version: 9.34 (I as a non techie regular user find too frequent updates - unlike other software - not worth it).

A bit of googling will get you the answer to this question.

Its probably your settings in Viewer Preferences - like the one highlighted in attachment - right ?

Similar but not exactly the same. The highlighted item is the same. I didn't change anything, I use default settings.

I would greatly appreciate if you or anyone gives me the correct terms to Google which brings me to the solution.

I tried Googling before asking this question, like:
http://www.google.com/search?q=calib...nges+file+size
There you have it!

Thanks

where do you think it puts that last page number - under its hat

I'm not the original poster, but I would have thought the reader would save it to the viewer settings file. On my computer that's C:\Users\halo\AppData\Roaming\calibre\viewer.json. That file already contains the list of recently opened ebooks. I don't see why it couldn't also store the last viewed page or any other book-specific view information.

Modifying an ebook file by merely opening it is unnecessarily risky, particularly in light of the fact that there's already a file that could store the last page viewed.

Unnecessarily risky? That is a strange assertion. What does unnecessarily risky even mean in regards to bookmarking where you left off in a book. There is zero risk, only a programming decision on how to track the position you stopped reading the book.

If someone doesn't want the bookmark file added simply uncheck the option to Remember the current page when quitting.

That would assume you only use the calibre viewer on that machine - for me that's not the case.

I don't mind synching .epub files based on their mod date, there's plenty of gadgets to do that, but I don't know of any gadgets that selectively synch the contents of .json files.

Edit : There's also bookmarks - I exchange epubs with colleagues, and we use the the viewer's bookmark feature as a primitive annotation feature - they are also in the epub.file. Same as notes and highlights are when we exchange PDF files

I turn info-tips off in most programs, but Calibre is an exception, its info-tips are excellent, although they sometimes disappear too quick - some programs have a setting to specify the info-tip display time, maybe a tweak could be provided in Calibre.

However the Viewer Configuration screens don't seem to have any info-tips - I think they should have them, and at the same standard all the other calibre info-tips.

Or have a missed a setting

How can I remove all personal metadata from the EPUB (current, page, bookmars, I don't know if it has notes as on a Kindle?) with a single click? With Calibre or otherwise?

drjenkins · 07-18-2013, 07:52 AM

It's not a single click, but you can use the Modify ePub plugin to remove calibre bookmark files and other artifacts.

And you can run Modify against multiple books

I tested several EPUB reader software in the meantime. Conclusion: none, other than Calibre actually write inside the file. Other software use it intact, bookmarks are not stored in EPUB, but in the displaying software. I like the idea.

eschwartz · 06-30-2014, 11:28 AM

And I would prefer it like this. Bookmarks and place info is not a feature of the viewer program, it should be intrinsic to the book.

You can turn the setting off, or use a different software. It is a personal choice, so I don't think Kovid will change calibre for that reason.
