As many of you are aware of [and those who aren't], Unswindle.pyw is no longer working with the new version of K4PC. [as of May 20th anyway]. While you can work around it with installing an older version of K4PC, you have to delete the new one, delete all files relative to it [ie, my kindle folder, etc] and turn off autoupdate. And I can guarantee that K4PC will eventually force you to update anyway :-)
So, Unskindle is still working. Download it HERE or HERE. Install to C:\skindle. Makes life easier, trust me.
Now, to de-drm your mobi, azw or prc book.
skindle [-d] [-v] -i -o [-k kindle.info file] [-p pid]
-d optional, for topaz files only, produce a decompressed output file
-i required name of the input mobi or topaz file
-o required name of the output file to generate
-k optional kindle.info path
-v dump the contents of kindle.info
-p additional PID values to attempt (can specifiy multiple times)
So to decode a non-Topaz file you should do the following:
1. In Windows, create a new folder and copy in the skindle.exe program, and copy in the book you want to remove the drm from
2. open a terminal (run command.exe) and use the cd command to change directories to your new folder (the one with skindle.exe and the book in it).
3. type in the following command line
skindle -i NAME_OF_INPUT_FILE -o NEW_NAME_FOR_OUTPUT_FILE
replacing NAME_OF_INPUT_FILE and NEW_NAME_FOR_OUTPUT_FILE as appropriate and it should do the rest.
And now an example:
1. If you are using Windows, create a separate directory for skindle such as C:\skindle
2. Copy the book you want to work with into this same directory. Looks like this: Superbook.azw
3. Open a dos window. Start – All Programs – Accessories – Command Prompt
4. go to the skindle directory. CD C:\skindle
5. To convert type as follows:
skindle -i superbook.azw -o superbook1.azw For non-Topaz
skindle -d -i suckerbook.tpz -o suckerbook1.tpz For Topaz
Output file name must be different from input name and no spaces are allowed in the file names.
Finally, to convert azw files to other formats, simply use Calibre, a free ebook manager that also allows you to change the formats of your drm-free ebooks quite easily.
