Delphi RTC Portal extension

This project requires a developer with a license and strong experience in Delphi's RTC Portal component. So for developers interested, I assume that you already know what RTC Portal is. Although the RTC Portal system includes file transfer system it doesn't include a file browser/explorer. Files transfered are stored in a desktop folder. What I want from you is to add file explorer support so I can remotely copy files from all folders/to all folders, delete files etc...
