Yes. The sender of a transfer gets an email that informs about the download of a file transfer. Also he is notified if the download expires without having been downloaded. In addition to that, there is a central log file that only administrative users can access. You can configure logging options to keep track of the details you want to see and hide those you don’t want to log.
It is possible to log the point in time when up- or downloads have been made, the sender and recipients’ IP and email addresses, filenames and sizes as well as texts and subjects entered by the users.
