Some time ago I wrote an article How to send PDF to Amazon Kindle via email and today tutorial with similar topic. This time we will not be sending the PDF Ebook (or other PDF file) via email but quickly upload it from PC with USB cable. I assume that you have your file somewhere in your PC ready. For the purpose of this tutorial I will upload ‘Sample_file.pdf’ that is located on my Desktop. Here’s what you need to do…
#1 Connect your Kindle to PC via USB cable
I have got an older version of Kindle Paperwhite, but in your case should be the same. At the bottom of the device there is a micro USB port. Plug in the USB cable to this port and connect the cable to the PC.
Once you connected your Kindle to your computer, a small window should pop out (File Explorer) showing you on the left all the file structure of your PC (I think this is the default behaviour, if your PC asks what to do, chose ‘Open device to view files’). It should also list your Kindle as one of the drives.
You may also see other icons for particular locations on the drive, like Desktop, Downloads, Documents, Music and so on. At the very top my Windows displays also some other folders I frequently use. This is how it looks on my PC:
#2 Create a folder on your Kindle for new files (optional)
This step is entirely optional but if you want to keep things tidy, I think you could create a special folder (or folders) for all files you transfer outside of Amazon Marketplace. You can store in your device hundreds if not thousands of books so keeping it nicely organised is a good idea.
Important point, in order the Kindle could read the files, they need to be in document folder of the device. So when creating your special folder, make sure you create in inside the documents folder and not in the root directory. To do so, click the documents folder in you
Kindle on the left (the content of the folder, all your ebooks from Amazon and other files, should be displayed). Then right-click, and from the small menu Choose ‘New’ and then ‘Folder’:
You can name your new folder anyway you like, I have chosen ‘Files from PC’.
#3 Find PDF file you want to transfer
In the File Explorer you probably see the content of your Kindle device (in my case it was two folders) but now you need to find the PDF file you want to transfer. You need to navigate into the correct folder by clicking on the locations on the left. If the folder contains other folders, you can click the grey arrow on the left of to display those and ‘go deeper’ into the folder structure. If you struggle and for some reason cannot find your file, write the file name in the search bar in the right top corner.
As I mentioned, my file is located on my Desktop, so I just clicked Desktop icon to display it. Here’s how the window looked like (green arrows shows the file I want to transfer):
Of course, your view may be different if you use different view settings, you may see the list or Extra large icons.
#4 Drag and drop your file from hard drive to the correct folder on your Kindle device
Once you found the file in question, you need to copy it to the correct folder on your Kindle. If you followed my instructions in step 2 and created special folder, copy it to this folder. If you haven’t bother to do so, copy it to the document folder. You copy the file be dragging and dropping it. If the folders on your Kindle device are not visible, click the little grey arrow on next to it (to display all folders in document folder, click again on the grey arrow next to it)
So on the right-hand side you can see the file you want to transfer and on the left you can see documents folder or your new special folder in your Kindle device. Drag and drop the file into the correct folder (I am copying my file to my new folder ‘Files from PC’ located in documents folder):
Depending on the file size, it should transfer within a few seconds (if the file is large you will see the progress of the operation on the screen). That is all, the file is on your device. You can right-click on the Kindle icon and choose from the menu Eject and then disconnect the device.
Important! If you transfer your file to the root (top of the folder tree) of the Kindle, you device will not read it 🙁 The file needs to be:  either document folder or  inside other folder that is in document folder.
The file you just transfer should be visible on the home screen of your device, tap it to open.
