Ok, I tried this, using the .exe, and it run across my Kindle (300+ books) and it ended with the following output:



However it hasn't worked - there's a "both" mobi/KF8I deliberately put on my Kindle today to test that didn't show with a cover, and it still doesn't show a cover after running the above

The tool extracts cover from AZW3 and mobi and saves it to tour Kindle. Thats all. So if your book does not have properly set up cover (use Kindle Previewer to check it) the tool will do nothing.

I've got it working on the 1 book as a test - I removed all books except that 1 from my Kindle, and ran it, worked fine.

Not sure what the error above was, but it stopped it from working.

If I wanted to run it in Terminal on my Mac, how would I set the variables you mention?

Sometimes with huge book list program crashes yourself for unknown reason. I suspect that there is IO bottleneck (Kindle memory is slow). In such cases you should simply rerun app and it should start from a point just before crash and should works fine.

On Mac you should download source file from: https://github.com/quiris11/ExtractC...ive/master.zip
1) Unpack it. For example to Download directory:
Code:
~/Download/ExtractCoverThumbs-master
2) In Terminal type:
Code:
python ~/Downloads/ExtractCoverThumbs-master/ExtractCoverThumbs.py /Volumes/Kindle
Your Kindle after connecting USB always is mounted to /Volumes/Kindle directory

The problem is in your filename (you use RIGHT SINGLE QUOTATION MARK: http://www.fileformat.info/info/unic...2019/index.htm). In source tree I fixed the problem quickly and dirty: https://github.com/quiris11/ExtractC...ce7c57e1e372be but the exe file is not yet updated.

Couple more questions:

1) Does it have to point to a mounted Kindle? Or will a "documents" folder full of .azw files on a hard drive work?

2) Would it be possible to turn this into a Calibre plugin?

You can process files on your hard drive, but you should recreate following directory tree:

Code:
Kindle  –
         |
          – documents
         |
          – system –
                    |
                     – thumbnails
So if above Kindle dir is on C:\ fire: ExtractCoverThumbs.exe c:\Kindle

This is brilliant, thanks.

Would the Calibre plugin be possible?

Ok, this works great, thanks.

Why does Amazon not fix whatever problem it is that you're solving with this?

Highlights:
1) It extracts only cover from a book file (entire process is quicker)
2) It adapts cover thumbnail to avoid Personal tag overlapping thumbnail.
