Class FTPFileFile

java.lang.Object
  extended by java.io.File
      extended by com.mindtree.techworks.insight.download.ftpbrowse.FTPFileFile
All Implemented Interfaces:
java.io.Serializable, java.lang.Comparable<java.io.File>
public class FTPFileFile
extends java.io.File

This class is a wrapper for FTPFile. This class is to be used by JFileChooserwhich requires an instance of File to it.

Most operations on the file wrapped by this class are not allowed . FTPFile is meant to contain information about files on a remote server, and FTPFileFile is also meant for the same. It merely provides a File like interface to FTPFile.

For any operations on the file, use the information about the file from an instance of this class and use FTPClientor any wrapper around it. You might use any other FTPClient also.

The getHostURLand getPasswordAuthentication methods return the host and authentication information to connect to the host.
