Converting from Epub vs ORIGINAL_EPUB

meghane_e · Yesterday, 12:34 PM

I'm running Calibre 8.8 right now. I had an unusual conversion happening where it kept using the ORIGINAL_EPUB file to convert from and not the existing EPUB format.

After I removed the ORIGINAL_EPUB file, it converted correctly.

Just wanted to post this before I forget it ever happened. This seems like a bug. I'm updating to 8.9 Calibre now. I'll double-check that 8.9 converts as expected.

Thanks!

Calibre will always use the ORIGINAL_EPUB file when reconverting.

See
Release: 0.8.11 [22 Jul, 2011]
New Features

When doing a conversion from some format to the same format, save the original file

When calibre does a conversion from the same format to the same format, for example, from EPUB to EPUB, the original file is saved as original_epub, so that in case the conversion is poor, you can change the settings and run it again. The original is automatically used every time you run a conversion with that format as input. If you want to disable this, there is a tweak that prevents calibre from saving the originals in Preferences->Tweaks. You can easily replace the converted version with the original in the Edit metadata dialog by right clicking on the list of formats in the top right corner.

Not always. When using the Modify ePub plugin, it will not use ORIGINAL_EPUB. But it will create one.

Curious: where did you get the release notes from 2011?

Version 0.8

Does it have mold?
That is over 10 years old.

I found another forum post discussing this and copied from there!

FYI, all release notes going back forever (version 0.6 IIRC) are available in the calibre repository in the file Changelog.old.txt

Can we have an option to not automatically use ORIGINAL_EPUB and have it there as a safety backup?

Quoth · Today, 09:22 AM

I always have a copy outside of Calibre on the same computer, so I delete "ORIGINAL_EPUB". Everything is backed up.

I went to:

Preferences / Tweaks / Save original file when converting/polishing from same format to same format

and set both options to False. Like Quoth, I can get back to the original version outside of Calibre if I need to.

I put the original into the Book's data folder irregardless of what I might then do or not do - i.e. convert, edit, modify, whatever. Preserves the original file name & modified timestamp, gets backed up on site daily, to cloud weekly, and I know where to find it.
