I'm not completely sure I understand your question, but I'm going to assume that you want the contents of a file, given the path to that file, provided as a Socket.IO event.

// var fs = require("fs");
socket.on("sendpath",filepath){
    fs.readFile(filepath,function(error, filedata){
        if(error) throw error;
        else socket.emit("sendfile", filedata.toString() );
    });
});
