When I first purchased my PW a few months ago, I noticed that many of the books which I sideloaded onto the device weren't showing up. These were books which I'd downloaded from Amazon or from sites such as MR. I sideload because I have no wifi.
During the warm weather I've got the urge to read more than I have been doing lately, so decided to load more books onto my Kindle. When I hooked the kindle up to my pc, I was shocked to see that I'd already put many books on it, but only 14 were showing.
These were a mixture of public domain books and some downloaded from Amazon. They were showing as in folders with the format .sdr. I looked inside the folders, they all contain two items with the format .mbp1 and .mbs.
I don't know what any of these formats mean. I tried taking them out of the folders and just putting the folder contents into the 'documents' part of the kindle, but this didn't work either.
What can I do about this please? Surely I shouldn't have to convert something which has come from Amazon?
Thanks for any advice.
