TCP/IP P2P

Summary -> Specify folder path to create and work with Send & Receive folders.. -> Specify a server IP address. The server serves multiple clients. -> Send & receive files, deleting sent files from the Send folder. -> No port forwarding, log events and ensure optimal performance. I am hoping to see something already done and working fast with options to customize it otherwise knowledge and experience is desirable in TCP/IP & P2P. It must send and receive a file, any file, from one pc to another without port forwarding. The application should have a folder for send and a folder for receive. The location of the folders as well as the other pc's IP address should be specified in the application. The IP specified is for a static server IP. When a file or files are copied to the send folder they must be deleted once sent. It doesn't matter what programming language it's created for but let's hope it's performance and stability is flawless. Interface mustant be complex but it should show and keep daily logs. let's see a demonstration that it has two folders for send and receive so it can receive file to send and receive Let's say one app that somehow could manage two folders so they react and sync One app like 5 clients and 1 server? could it be possible to have multiple clients sync to one server? send and receive folder will be managed with other software but this is an upload scenario? Only uploads and not like allow the server to download from another PC Functionality is desired some way that is fast and dependable You may notice that there is no security protocol. It would be fine if you need to use SSL but for sure atleast we need to be sure that the port traffic is meant for the application if there is no security. and that may go along with there just being a need to have connection monitoring. Impress me but keep the app small and simple. --- Obviously I am looking for a better deal than 250 usd. When I say that I am looking for already working applications it obviously means I should pay less. I don't understand paying top budget for simple work. --- UDP is an unreliable means of file transfer that should not be used. A demo will be nice either video or a executable or code. Chat and file attachment is fine but the app should have a priority on optimal execution of TCP-IP functions. Let's ensure that the file meets it's destination fully intact and that it's very fast, secured by port validation of some sort and that the connection is managing to reconnect.
