Hi everybody , I'd like u to help me to increase the file size that will upload or download between client and server " now i can send or receive 70 mb but once i want to increase the size to for instance 300 or 400 MB it doesn't accept
Here is part of the code
Server code :
Code:

public Socket sock = null; //server socket for connection management
public int servPort = 0; //server Port number
public DataOutputStream fileDir = null; //to sent shares file name
public DataInputStream selectedFile = null; //to accept client selected file name
public DataInputStream command = null; //to sent or receive file
public int clientConnectStatus = 0; //0 = client connect for the first time
public int fileShareList = 0; //0 = sending file share list for the first time
public Thread readThread; //mainThread to handle connection for server
public File Filelist [];
