copy whole directory in java

Java's not real good at that. You have to actually open every file, read it and write it to the copy file.

If you don't need a x-platform solution it's probably a lot easier to use exec() to call the relevant DOS command to do the copy.

Hi objects,
   How are you? Thanks for your previous help.
   regarding your recommendation :

"If you don't need a x-platform solution it's probably a lot easier to use exec() to call the relevant
DOS command to do the copy."

   Can you explain in detail how can I use exec()? Is it call from my java code?
   Thanks.

Something like:

    Process proc = Runtime.getRuntime().exec( "DIR" ) ;
    BufferedInputStream is = new BufferedInputStream( proc.getInputStream() ) ;
    byte[] buf = new byte[ 4096 ] ;
    int cnt = 0 ;
    String out = "" ;
    while( ( cnt = is.read( buf, 0, 4096 ) ) != -1 )
    {
      out += new String( buf, 0, cnt ) ;
    }

then the String "out" will be a directory listing...

Good luck,

Tim.

why not use
new File("c:\\directory").list();

I think java is the way to go.
my experience shows me, that using exec is something one need to avoid, because in most cases, it make the program not just platform dependent, but also COMPUTER dependent.
(ie - working on just one computer).

// Execute native command
Process proc = Runtime.getRuntime().exec("xxxx");
// Wait for command to finish
p.waitFor();

where xxxx is replaced by the DOS command to do the delete.

I will still need to go through to fully understand this, but this code just simply WORKS.
I only had to add a missing import for it, importing java.io.FileFilter for class header FileUtils.
Then, I was copying a folder over a network connection and it just worked fine.

Great code, thanks.
