public class FileTransfer
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.
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();
