Calibre as function to do just about anything you you need to. To remove any format of a book, you select the book and right-click on the format in the details pane and select delete. Or select set of books, right-click on the delete button, or right-click on the books in the list and select Remove Books, then select the "Remove files of a specific format from selected books". In the dialog, select "ORIGINAL_EPUB" or whichever format you want to remove. Have you tried my suggestion for how test with a book? |

It's problems like this why it's never good to send eBooks in bulk. Even Kindles can have a problem with an eBook getting stuck indexing.
Go with @Ripplinger's suggestion and if it works, then you'll be able to find which eBook it is that's causing the problem. |

If it's just an individual book, in the Book Details column usually at the right, you can right-click "ORIGINAL_EPUB" and select "Delete the ORIGINAL_EPUB format". If you have many books with a format you want to clean out, use the left hand column under Formats, click on ORIGINAL_EPUB, and it will list all books that have that format. Select all the books, right-click, select "Remove books", "Remove files of a specific format from selected books", click on ORIGINAL_EPUB, then OK, and it's all done in a few seconds. There is no reason to make an enormous amount of work out of it by opening every file folder in your library. But I would still caution against removing them without checking that the layout is how you expected it to look. Again, just through Calibre's interface, no need to go opening every folder. Edit: Now that I've read the rest of the posts, this is exactly what davidfor said above, just clarified a bit more since it sounds like you're not very familiar with Calibre's functions.

This afternoon I removed everything from the Kobo except the four books I'm currently reading and fully charged it. After reading a few times and letting it sleep the battery has discharged to 64%, so that didn't work.
My next step is to completely reset the reader and, again, load the same four books, but only after doing an epub to epub conversion on all of them. Just out of curiosity, I only notice this drain after it's been closed with the sleep cover. I can't imagine that having anything to do with it, but would it make any sense to remove the sleep cover? My wife's reader has the same cover and it's not doing this. |

Have you tried swapping sleep covers with your wife to test this out?

If there's a way to identify the rogue book(s) in the Calibre library itself, that would be useful. |

It occurred to me simply to do a hard drive search for "ORIGINAL_EPUB" which brought every one of them up in my finder, and then delete. Of course, they remained in my Calibre library but I figured out how to "fix" that.
I've reloaded the three books I'm reading after a factory reset, and now I'm recharging - again - to 100%. If the drain normalizes then I'm looking at a situation where whatever book it is that's causing problems is corrupting the Kobo to the point where simply deleting it isn't sufficient. Might be best to just to epub-epub convert the entire library before I start reloading if that's the case. |

I just went ahead and converted everything and one book refused to convert, so I tossed it. Whether or not that one was the problem remains to be seen.

If you can recover it, please consider sending it to davidfor for analyzing (in case that book was the problem).

then convert .TXT to .Epub file. this what I do to remove dodgy formating. then download and use kepubify command to convert to .kepub.epub (kepubify -o "converted" *.epub) To batch convert a directory of ebooks: kepubify /path/to/the/books/ e.g. kepubify -o "converted" *.epub (to convert all books in current directory and place converted .kepub.epub files in directory named converted) Last edited by raygj; 01-16-2021 at 07:56 AM. |

After having removed everything, resetting the Kobo, and loading just one book on it, it STILL was losing power while sleeping.
So I removed it from the sleep cover, and the problem stopped. WTF? How can a sleep cover cause such problems? I know the Kobo was sleeping when the cover was closed - the light went off and it was obviously sleeping when I'd open it. |
