Hey guys. So I just bought kindle paperwhite 10th gen, and still figuring out new things every now and then, and I've been transfering a few pdf files from my laptop to my kindle device via data cable. I notice that those files doesn't appear in my amazon account except those that I actually downloaded from amazon store. Is there any way I could automatically sync those folders to my amazon account without doing so via data cable? Cause I've been highlighting a few of them.
and your highlights would have been there. Unfortunately, there's no way now to sync the highlights on the ones you transferred via usb to your account The only thing I can suggest is to use Send to Kindle in the future.
