Problem in copying directory in Win-NT

[sonal verghese]

Hi,
I have made a backup program which creates a destination directory and then copies a source directory to this destination directory. In Win 98, I used xcopy32.exe from c:\windows\command and it runs properly. But when I try this program in a Win-NT m/c I face the following problems:
1. I changed xcopy32.exe of win 98 m/c to c:\i386\xcopy.exe in NT m/c. Still the program does not work and gives no error. The message shown is:
Directory created
0 files copied.
Though there are many files in the source directory. Please help me. Thanks in advance.
My source code is:

import java.io.*;
import java.util.*;
class BackUp {

static File directory;
static File destination;
static String destDir;
Thread t;
static String fileArray[];
String destinationDir;
String sourceDir;
public static void main(String args[]) throws IOException, InterruptedException {
int i;
directory = new File(args[0]);

destDir = (new Date()).toString();
destDir = destDir.substring(4,19);
System.out.println(destDir.substring(4,6));
fileArray = list(destDir.substring(4,6));
System.out.println("Length " + fileArray.length);

destDir = (destDir.substring(0,3)+destDir.substring(4,6)+destDir.substring(7,9)+ destDir.substring(10,12)+ destDir.substring(13,15));
destination = new File("D:\\backup\\" + destDir);
System.out.println(destination.mkdirs()?"Directory created  " + destination:"Directory cannot be created");
if (!destination.exists()) {System.out.println("***********STOP******** Do Not Proceed with Deletions.."); System.exit(0);}
//System.out.println("c:\\windows\\command\\xcopy  "+ args[0] + "\\     " +   destination.getAbsolutePath() + "\\" + args[0].substring(3,args[0].length())+ "\\  /s");

Runtime run  = Runtime.getRuntime();
System.out.println("c:\\I386\\xcopy.exe  "+ args[0] + "\\ " +   destination.getAbsolutePath() + "\\" + args[0].substring(3,args[0].length()) + "\\  /s ");
Process p = run.exec("c:\\I386\\xcopy.exe  "+ args[0] + "\\ " +   destination.getAbsolutePath() + "\\" + args[0].substring(3,args[0].length()) + "\\  /s ");
BufferedInputStream br = new BufferedInputStream(p.getInputStream());
int r = br.read();
do{
System.out.print((char)r);
r = br.read();
}while(r != -1);
p.waitFor();

}

static String[] list(String exten) {
FilenameFilter only = new Filter(exten);
return directory.list(only);
}

}// end of class Back up

First - was this WORKING in the WIN98 environment???
Second - what class is Filter??

I was able to solve my problem. Here is the solution:
Sonal,
In the best interest of the JavaRanch community, I would love to help with the problem you are having. Please post the text of your mail to the public forums so that everyone can benefit from your experience. There is probably somebody else that wants to do what you are doing and is having a similar problem.

P.S. Your problem is in your use of xcopy, not your Java. Try it like this:
xcopy c:\SourceDirectory\*.* c:\BackupDirectory /s
without the trailing \ on your backup directory and be sure to use the *.* in your source argument. When I used your syntaxt I got "Invalid Path - 0 files copied". When I modified the syntax lightly, I got it to work just fine.
Thanks to all.
