.MOBI Files – Most mobile phones can read this file type, but may require additional software to open. Some notable free programs that can open MOBI files include Calibre, Stanza, Sumatra PDF, Mobi File Reader, FBReader, Okular, and Mobipocket Reader. MOBI files can also be read by popular eBook readers like the Amazon Kindle and many smartphones that support the format. ** Files must be e-mailed / sent to your Kindle address to open them on your Kindle reader.
.PDF Files – Adobe’s Acrobat Reader is the official tool for reading PDFs. It’s free, and it’s available for Windows, macOS, iOS, and Android. After installing Acrobat Reader, all you have to do is double-click on any PDF you want to open.
