I'm having some problems using Calibre to rename books that I bought from Amazon. Whenever I rename them I seem to lose X-Ray functionality, not sure if it's because of Calibre or if X-Ray is linked to the name. So far I just avoided renaming the files but as my library builds up it's getting more and more unorganized (even using the categories function on the Paperwhite). If anyone knows a simple solution around this it would be a great help!
