Conversion Question
I used Calibre v2.83 to convert a Kindle Book to epub. The file did not have DRM protection and seemed to convert fine. However, when I try to open the book on my Nook HD or Samsung Galaxy Nook, I get an error and the book will not open.
The book will load and open properly when using the Nook App on my PC. Any ideas of why this is happening and how I can get the book to open on one of my Nook Tablets? Thanks in advance for any help. |

Convert your book to MOBI, then convert the MOBI to EPUB. That will destroy any advanced formatting, but it might workaround whatever the problem with the tablet app is.
Or just use a better epub reading software on your tablet. |

I tried converting to MOBI, but still have the same issue - No idea what the issue is, as all I get is an error message saying "Cannot open this file"
I don't think it is the ereader software, as it only happens occasionally - most books open without any issues. Any other ideas? |

Conversion in calibre leaves the converted ebook in the calibre library on your computer. The reader software on your device(s) can only read ebooks that are stored on the device. Somehow, you are copying or moving the converted file to the device. Exactly how???????? |

I use the USB cable to transfer the epub version from the computer to the Nook. I open the Nook on the computer through the USB cable, then do a copy and paste to the folder I created on the SD Card.
Most books open without any issue and only occasionally yield an error. |

I tried getting Calibre to recognize and download books from a Kindle Fire, but this seemed to have issues too. I am very comfortable with technology, but this problem has me stumped. |

The configuration for each driver can be changed with what is the preferred format and the location to put the books. |

Okay, I understand that you say I should allow Calibre to determine the format. This still does not explain why most files open the way I was doing it, but others do not open. Nor does it explain why a file will give an error when trying to open it on the Nook, but will load in and open on the Nook App on my PC.
I am trying to understand the inconsistency. |

Someone probably made a monolithic (1 xhtml file) Epub you PC can handle that. ~600 KB per 'section' was the max my old PEz (ADE) could handle. Many of us still work with Chapter/file for ease of edits and performance YMMV |

Also, if the issue is due to a software issue, why do I see the same issue on both a Nook HD (several years old) and a newer Samsung Galaxy Nook? |

File size limits in Digital Editions EPUB 3 : 300kb HTML file size limit That is the spec. But most ereaders and e-book reader apps can not handle a file size over 260kb, I know from experience that a Nook can and will some times fail on a 260kb file. bernie |

You'll probably find the Larger Boxed Sets are split into several XHTML files, perhaps one XHTML file per chapter and they're all less that 260KB; whereas the recalcitrant books probably have a single much larger XHTML file. A book can be split into 'Chapter' files is via the Conversion Structure Detection options, another way is to use the splitter tool in the ebook editor. No doubt there other ways too. BR |

Inconsistent errors can drive you crazy! Quick question to confirm what you've said: "Most books open without any issue". Are you saying that most books that have been converted from Kindle to ePUB open without issue? Or, is it just the books that did not need conversion to ePUB that open without issue? |
