In addition to features found in other popular FTP clients (like support for the SSL/SSH, multipart and multithreaded transfers, file filtering, direct server-to-server transfers or transfer scheduling) BitKinex introduces several unique approaches and solutions like: browse windows which never freeze, indirect transfers allowing to copy files between servers running different transfer protocols or inherited properties enabling easy and powerful configuration. The application communicates with you via a highly scalable user interface which doesn't disturb you from your primary tasks. With just one click you can minimize the space occupied by BitKinex to one small window showing the status of running requests, and with just a few clicks you can see all the details again.
