Richard (or any of the team), Assuming that the user is using OS X, use of standard VFS, access on a local disk, no ATTACH, no Jedi mind tricks ... Does SQLite ever close and reopen database or journal files between _open() and _close() ? An example of a time I might expect this would be during a VACUUM, or as a transaction finishes while journal_mode = DELETE. My guess is that if SQLite closes one of these files it creates a new one with the name and path it already knows, but I wonder if it might close and reopen one of these files. Of course, if it closes a file you've moved, then tries to delete it, it won't be able to delete it.
