This is an implementation of a simplified version of FTP. This program consists client and server. The server is responsible for serving files to the client.
In this protocol, communication requires two different channels to send and receive data. The first channel, called the command channel, is the channel through which commands and responses are sent. The other channel, which is called the data channel, is the channel responsible for data transfer. Also, a file called config.json exists, which holds information about both users and the command channel and data channel port for authentication and authorization.
