xx = file_id % 256, in hexadecimal
file_id = book identifier index inside global.db
This way we could provide a two way conversion between "classic" format (with thumbnails inside the db) and new format.
Now I have to complete the code to handle file deletion and finish the migration tools.
That is a brilliant move, using the unique file_id from global.db. I pushed a solution based on your previous code to BitBucket a few days ago. But this will make it more easy I guess.
