Kind of recent to NC CM7, but very tech savvy. Using SwiFTP to transfer files (.epub/.mobi) to the NC. Had an issue where I copied a group of .mobi files to the /mnt/sdcard/kindle folder on SD card. I then tried to Open the Kindle app and it gave an error msg. So I narrowed it down to the file transfer. Once I deleted the files I copied it started working again. So how to I check for BAD .mobi files ?
