public class FileTransfer extends ByteArrayTransfer
The classFileTransferprovides a platform specific mechanism for converting a list of files represented as a javaString[]to a platform specific representation of the data and vice versa. EachStringin the array contains the absolute path for a single file or directory.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();- Since:
