How To Convert Pre-Kindle Ebook Files. I have ebooks, mostly .Exe files and I would like to convert to e-reader compatible files. Not just Kindle but also other e-reader platforms. I feel sure you all know the kind of stuff I'm talking about. All those EXE files we downloaded before Kindle came on the scene. If this is possible . . . what software tools do I need. Thanking you in anticipation for your help and assistance . . . Be seeing you.
