public class FileTransfer
extends ByteArrayTransfer

Untamed: The class FileTransfer provides a platform specific mechanism for converting a list of files represented as a java String[] to a platform specific representation of the data and vice versa. Each String in the array contains the absolute path for a single file or directory. See Transfer for additional information.

An example of a java String[] containing a list of files is shown below:

     File file1 = new File("C:\temp\file1");
     File file2 = new File("C:\temp\file2");
     String[] fileData = new String[2];
     fileData[0] = file1.getAbsolutePath();
     fileData[1] = file2.getAbsolutePath();
