Adventrures and Problems with ~.AZW4
So I recently downloaded a few textbooks from amazon only to find that they are in the new .azw4 format.
I was able to strip the DRM from the books by [Detailed DRM removal instructions removed by moderator]. Now this is where I start to have problems. If I open the files with Amazon's PC reader, the .mobi files work fine. If I import them to Calibre, and try to open them, all I get is the first two pages, or it doesn't even open. If i try to convert the .mobi file to an epub, it does not work. Looking at the log, I get a Python Error and then a little while later a memory error. Code:
Extracting text... Python function terminated unexpectedly (Error Code: 1) Traceback (most recent call last): File "site.py", line 132, in main File "site.py", line 109, in run_entry_point File "site-packages\calibre\utils\ipc\worker.py", line 181, in main File "site-packages\calibre\gui2\convert\gui_conversion.py", line 31, in gui_convert_override File "site-packages\calibre\gui2\convert\gui_conversion.py", line 25, in gui_convert File "site-packages\calibre\ebooks\conversion\plumber.py", line 937, in run File "site-packages\calibre\customize\conversion.py", line 204, in __call__ File "site-packages\calibre\ebooks\mobi\input.py", line 27, in convert File "site-packages\calibre\ebooks\mobi\reader.py", line 312, in extract_content File "site-packages\calibre\ebooks\mobi\reader.py", line 877, in extract_text MemoryError I was wondering if anyone had any ideas as to what might be happening.

azw4 is not a mobi file. its is a PDF embedded inside a MOBI wrapper. The next release of calibre will allow you to convert azw4 files, but since they are pdfs the conversion will suffesr from all the problems of pdf.

It's out already! calibre 0.8.17 can now import drm-free Print Replica files (e.g. sample files).

And if you consult Apprentice Alf's blog, I think you'll find that there's now a calibre-plug for azw4 files.

Since I'm quite interested in buying textbooks from Amazon, does anyone know if I can extract the PDF from the AZW4 file (after proper DRM-stripping, of course)?

*note: I have the Calibre version 0.8.37 and it is not properly viewing/converting my AZW4 file. I can open it for viewing but it looks a total MESS! Help is greatly appreciated! (especially since Kindle and Nook don't allow textbook viewing on their devices... atrocious!) |

The Mobiunpack script is a stand-alone python script. You'll need to install python to run it if you're on Windows. |

MobiUnpack is a perfectly legal program that can be discussed here at Mobileread without any problems at all.

Are you on Windows? Did you properly and fully install ActiveState ActivePython 2.7.x as instructed?
If you open a terminal window (run cmd.exe) and type python and hit return, what does it say? More help is available via the "New Mobi Decoder" thread in the "mobi" forum here since this really has nothing to do with Calibre specifically. Quote:

This works great. Thanks so much for allowing me the use of the book that I purchased. I have just one question. What do I do with all of the .data files? Is it safe to delete these?
Thanks Again, |
