It was introduced a few revisions ago as part of making Calibre more robust after failures. The metadata.opf file just has a copy of the the metadata for the book it is associated with that was previously only held in the Calibre metadata database. It can be used to recover a corrupt Calibre database, and also has the merit that it holds ALL the metadata even if the format in use does not support it so can facilitate transfering books between systems with all the metadta transfered.

I would not have thought that Aldiko will require it?
