* origin initialization. A file is orphaned when there's a file with zero size
|
|
* in the $dbName.files/journals directory and the file table in the database
|
|
* contains no records for given id. A file can become orphaned when we didn't
|
|
* have a chance to remove the file from disk during shutdown or the app just
|
|
* crashed.
