Thanks for that, I searched for ages and didn’t find it, maybe a bit more added to the help sometime would be useful.

So do you drop the index file or will it work if you dropped just one of the files referenced in the index files. If say you are creating the document in say word in a folder other than the ebooks tree will dropping the new file in document details also then update/replace the source one for Calibre?

I do kind of like the way Libre Office allows the Master file to take in files of different formats. Makes me think how useful it might be if the html file was also a way of inputting file in formats other than html or maybe even if Calibre could process the Libre Office odm (Office document master) file. Generating the merged file from the odm file is a couple of steps more than it could be IMHO.
