title_body: Where is my Ebook that I just bought from Amazon Kindle to my PC? I am new to Amazon Kindle ebooks. I am using my computer to read Kindle ebooks. I am using Kindle-for-Pc software. I just downloaded an ebook, but I cannot find it anywhere. I need to find it so that I can backup in my flash drive, in case something happens to the computer. I can perfectly read the book from the Kindle-for-Pc program, but I need to find the actual ebook, since it was not free and I don't want to lose it.
upvoted_answer: I have Windows 10 and also use the PC software. Mine are stored in my "Documents" folder in subfolder "My Kindle Content". That would ordinarily be "%HOMEPATH%\Documents\My Kindle Content", but I have changed the location of my Documents folder to another drive.
  
  On the Kindle app's toolbar go to "Tools|Options..." and click on the "Content" tab. Here you will see the location of your files along with a button giving you the option to change that location.
