@robin58 - I use Goodsynch, matter of fact I just d/l latest version (9.7.9), and I'm using calibre 1.24

The calibre version number in the dc:contributor entries in my opf's appears to reflect the version number when metadata was last changed. Many of them have 0.9.nn in there, some might even have 0.8.nn.

'Tis a pity that there is no option to display the Library metadata backup status counter in the status line, then one could see them being written. You might be able to hear them being written - on my rig when there's a bulk change of opf's happening they are written at about 1 per 2 sec, so the drive sounds like a slow ticking... clock.

Maybe the file system modified timestamp on the opf files can give you a clue as to when they're being written.

Its my understanding that Kovid has not changed the database schema for a number of years, I assume he hasn't changed the opf schema for a similar time.
