I don't hold with the black box model either

But one needs to recognise that calibre is a database application. For reasons of efficiency and performance it uses the file system to avoid overloading the database with a BLOB for every format and cover image. This enables it to load a library database into memory, which is how it gets its search and sort performance. As a consequence the names of library sub-folders and files must be kept in strict synchronicity with the database.

So my rule is look but don't touch, i.e. no additions, deletions or name changes to the folders and files in a calibre library folder.
