I have an ebook type that I would prefer to have in calibre. So, here is a link to an ebook that came in this other reader (for free so no copyright issues here). Any help/suggestions on how to open this in Calibre and convert it to something else? Here is the link:

I had to zip it to put it on dropbox, but the original "ebook" is the entire folder contained within the zip, so you would need to unzip it to get it in its original form. Thanks!
