There are always a large number of metadata.opf files for books that I have not read or changed in any way.
It's not really a problem as they copy over quickly, but what could be changing my metadata.opf files?

Those files exist for calibre to use as backup data. They are changed whenever anything changes in the library that might affect the book. Examples: custom column changes, tag case changes, book metadata changes, etc.
