I have downloaded from Amazon.com two Bible files (paid for one, free the other) that have long file names. For convenience, I renamed them to ESV and KJV using "My Computer" before copy/paste to Kindle. I can "see" the files in the documents folder on Kindle with My Computer but Kindle does not display them to select/read.
The Kindle Help pages and files, like most help files, contain lots of useful information about all sorts of things but there is no mention of my problem. Could it be something to do with renaming?
