I just copied a couple of files there. In the browser window where I copied them, it correctly showed the sizes as 8 kbytes and 63 kbytes. When I re-open the same page, it shows them as "8 bytes" and "63 bytes". They download correctly. Is there a way to copy files other than drag-and-drop? That's not always convenient, and in some environments might not be possible. (As hanniabu points out, clicking on the drop zone opens a file selection dialog, so never mind.)
