Basic operation "free_space" is not implemented

$result = $this->basicOperation('free_space', $path);

The function public function free_space($path = '/') calls $this->basicOperation('free_space', $path); but basicOperation doesn't implement the operation "free_space" and hence always returns null.

In consequence, no free disk space is calculated and e.g. the trashbin retention will keep files forever.

At least for local storage free_space is correctly forwarded. I'm closing your report. Feel free to create a proper report using the issue template and include for which storage free_space is not implemented.
