Many eBooks come in the .mobi extension. This is the MobiPocket format. If you are trying to read .mobi content on the Windows platform, here are 2 pieces of software you can use:
1] Amazon Kindle eReader for Windows.
- You can find out more and download the Kindle for PC here: www.amazon.com/kindleforpc
- This is an excellent eReader for the PC
- One disadvantage is that you cannot export or share (at least easily) your personalized notes and highlights for non-Amazon store books – which include .mobi files.
2] Calibre
- You can find out more and download it here: http://calibre-ebook.com/
- Calibre is a good general purpose eReader that supports all major formats.
- It is much more than just a eReader though – it is a whole e-book library management piece of software
- The biggest disadvantage as an eReader is that it is a heavy footprint for just an eReader.
