First Things First
You need to download and install these apps on your computer. If you have any of them then you do not need to install them again:
Calibre is of course the ebook library management tool. I’ve mentioned it once or twice, and that’s what you’re going to use to remove the DRM. And K4PC is how you’ll download the ebooks.
Install the apps one at a time (and set up your account with the K4PC app, if you haven’t already). While they’re being installed, go download this ZIP file full of plugins:
Got everything installed? Good.
- UnZip the ZIP file you just downloaded. Open the folder called calibre and you should see a folder full of plugins.
- Launch calibre. When it’s open, look at the icons on the top row. There’s one on the far right called “Preferences”. Click on it. See Pic 1.
- It will bring up a new window with a bunch of icons. Look on the bottom row for the one that says “plugins”. Click it. See Pic 2.
And now you’ll get another new window. Look at the buttons on the bottom row. Click on the one that says “load plugin from file”. See Pic 3.
- Use the file browser window to find the folder you downloaded. Open it, and then open the DeDRM_calibre_plugin folder.
- There should only be a single ZIP file in that folder, and it should be called “DeDRM_plugin”. Double click to select it.
- Shut down calibre and launch it again. Some times the plugin won’t kick in until you after you do this.
You’ve just installed and configured the plugin (assuming all went well). You should be able to copy any ebook you’ve downloaded from the K4PC app to calibre. Calibre should now be able to read the ebooks and convert them to whatever format you prefer.
But before you can do that you’ll need to find out where the Kindle ebooks are stored. This varies depending on which version of Windows you’re running, but they can usually be found under the My Documents folder. I’m looking at my Win 7 laptop right now andthe Kindle ebooks are found in “My Kindle Content” under My Documents.
The ones you will need to copy are:
After you copy the files into calibre, you might have some trouble getting calibre to open them so you can read them. Windows will need to be told that calibre can open the files. This should only happen once, so it’s a relatively minor issue.
Note that if you simply convert the ebooks, you won’t have this issue.
Note 2: If you are having problem removing the DRM protection, try to drag your book to your Kindle, then import from the Kindle to Calibre. Oddly enough, that worked for me.
