The connect() method is used to perform the actual connection to the remote host - but only for this constructor. Deprecated constructors connect in the constructor and connect() is not required (and cannot be called).

  - cancelTransfer
```
public void cancelTransfer()
```
    Description copied from interface: FTPClientInterface
    
    Cancels the current transfer. Generally called from a separate thread. Note that this may leave partially written files on the server or on local disk, and should not be used unless absolutely necessary. After the transfer is cancelled the connection may be in an inconsistent state, therefore it is best to quit and reconnect. It may cause exceptions to be thrown depending on the underlying protocol being used. Note that this can also be used to cancel directory listings, which can involve large amounts of data for directories containing many files.
    
    Specified by:
    
    cancelTransfer in interface FTPClientInterface
  - isTransferCancelled
```
public boolean isTransferCancelled()
```
    Has the current transfer been cancelled?
    
    Returns:
    
    true if cancel, false otherwise

public void setPORTIP(java.lang.String IPAddress)
               throws FTPException
```
    Deprecated.
    
    We can force PORT to send a fixed IP address, which can be useful with certain NAT configurations. Must be connected to the remote host to call this method.
    
    Parameters:
    
    IPAddress - IP address to force, in 192.168.1.0 form
    
    Throws:
    
    FTPException
  - setActiveIPAddress
```
public void setActiveIPAddress(java.lang.String activeIP)
                        throws FTPException
```
    We can force PORT to send a fixed IP address, which can be useful with certain NAT configurations. Must be connected to the remote host to call this method.
    
    Parameters:
    
    activeIP - IP address to force, in 192.168.1.0 form or in IPV6 form, e.g. 1080::8:800:200C:417A
    
    Throws:

public void setActivePortRange(int lowest,
                               int highest)
                        throws FTPException
```
    Force a certain range of ports to be used in active mode. This is generally so that a port range can be configured in a firewall. Note that if lowest == highest, a single port will be used. This works well for uploads, but downloads generally require multiple ports, as most servers fail to create a connection repeatedly for the same port.
    
    Parameters:
    
    lowest - Lower limit of range.
    
    highest - Upper limit of range.
    
    Throws:
    
    FTPException

```
    Login into an account on the FTP server. This call completes the entire login process. Note that connect() must be called first.
    
    Parameters:

           throws java.io.IOException,
                  FTPException
```
    Login into an account on the FTP server. This call completes the entire login process. This method permits additional account information to be supplied. FTP servers can use combinations of these parameters in many different ways, e.g. to pass in proxy details via this method, some servers use the "user" as 'ftpUser + "@" + ftpHost + " " + ftpProxyUser', the "password" as the FTP user's password, and the accountInfo as the proxy password. Note that connect() must be called first.
    
    Parameters:
    
    user - user name
    
    password - user's password
    
    accountInfo - account info string
    
    Throws:
    
    java.io.IOException
    
    FTPException
  - user
```
public void user(java.lang.String user)
          throws java.io.IOException,
                 FTPException
```
    Supply the user name to log into an account on the FTP server. Must be followed by the password() method - but we allow for no password. Note that connect() must be called first.
    
    Parameters:
    
    user - user name
    
    Throws:
    
    java.io.IOException
    
    FTPException
  - password
```
public void password(java.lang.String password)
              throws java.io.IOException,
                     FTPException
```
    Supplies the password for a previously supplied username to log into the FTP server. Must be preceeded by the user() method
    
    Parameters:
    
    password - The password.
    
    Throws:
    
    java.io.IOException
    
    FTPException
  - account
```
public void account(java.lang.String accountInfo)
             throws java.io.IOException,
                    FTPException
```
    Supply account information string to the server. This can be used for a variety of purposes - for example, the server could indicate that a password has expired (by sending 332 in reply to PASS) and a new password automatically supplied via ACCT. It is up to the server how it uses this string.
    
    Parameters:
    
    accountInfo - account information string
    
    Throws:
    
    java.io.IOException
    
    FTPException

    Parameters:
    
    port - SOCKS proxy port
    
    host - SOCKS proxy hostname
  - initSOCKSAuthentication

```
    Set up SOCKS username and password for SOCKS username/password authentication. Often, no authentication will be required but the SOCKS server may be configured to request these.
    
    Parameters:
    
    username - the SOCKS username
    
    password - the SOCKS password
  - clearSOCKS
```
public static void clearSOCKS()

                          FTPException
```
    Use to find out if a file exists or not. Since there is no reliable standard command to check the existence of a file, this method first tries to get the size of the file. If this fails then it tries to get the modtime and finally, if that fails will get a directory listing and look for the file in that listing.
    
    Parameters:
    
    remoteFile - File of which to check existence.
    
    Returns:
    
    true if directory exists.
    
    Throws:
    
    java.io.IOException - Thrown if there is a TCP/IP-related error.
    
    FTPException - Thrown if there is an error related to the FTP protocol.
  - existsDirectory

```
    Use to find out if a directory exists or not. Since there is no reliable standard command to check the existence of a directory, this method tries to change into the directory and then changes back to the original directory.
    
    Parameters:
    
    remoteDirectory - Directory of which to check existence.
    
    Returns:
    
    true if directory exists.

public void resume()
            throws FTPException
```
    Description copied from interface: FTPClientInterface
    
    Make the next file transfer (put or get) resume. For puts(), the bytes already transferred are skipped over, while for gets(), if writing to a file, it is opened in append mode, and only the bytes required are transferred. Currently resume is only supported for BINARY transfers (which is generally what it is most useful for).

```
    Description copied from interface: FTPClientInterface
    
    Make the next download resume at a specific point. This resume method allows the resume offset to be set explicitly for downloads. Offset bytes are skipped before downloading the file. This means you can download only the last few bytes of the file rather than the whole file, irrespective of the size of the local file. Currently resume is only supported for BINARY transfers (which is generally what it is most useful for).

    Issue the RESTart command to the remote server. This indicates the byte position that REST is performed at. For put, bytes start at this point, while for get, bytes are fetched from this point.
    
    Parameters:

    Description copied from interface: FTPClientInterface
    
    List a directory's contents via a callback. The callback is notified for each directory entry, meaning they can be processed individually. It also avoids out of memory problems if the directory is huge, and an array of thousands of FTPFile objects would otherwise be returned. Most servers return an empty directory listing if a directory does not exist, and this is also what this method does. To establish whether or not a directory exists, try changing into it.
    
    Specified by:

```
    Description copied from interface: FTPClientInterface
    
    List a directory's contents as an array of FTPFile objects. Most servers return an empty directory listing if a directory does not exist, and this is also what this method does. To establish whether or not a directory exists, try changing into it. Should work for Windows and most Unix FTP servers - let us know about unusual formats (http://www.enterprisedt.com/forums/index.php). If accurate timestamps are required (i.e. to the second), it is generally better to use @see #modtime(String).

    List a directory's contents as an array of strings. A detailed listing is available, otherwise just filenames are provided. The detailed listing varies in details depending on OS and FTP server.
