Parameters

criteria: The filename or criteria for which to search.
options: An array of options for the remove operations executed against the chunks and files collections. See MongoCollection::remove for documentation on these options.

Fields in the status array are described in the documentation for MongoCollection::insert.

Errors/Exceptions

Throws MongoCursorException if the "w" option is set and the write fails.
