Hi senthilkumar
I hope I help you:
copy file:

File file = new File("path of source file");
if(file.exists){
FileInputStream fis = new FileInputStream(file);
FileOutputStream fos = new FileOutputStream("path of new file");
byte[] buff = new byte[fis.available()];
fis.read(buff);
fos.write(buff);
}

I have a folder which contains lot of text files and image files.
I want to copy all files from one folder to another.

senthikumar, you have already been asked once to change your display name to conform to the JavaRanch Naming Policy. I must warn you that if you do not comply, your account will be closed.
You can change your name here.
As for Kia's code, it has one fatal error: available() doesn't do what you think it does.
Have a look at this example for a copy method that works.
To copy an entire directory, use the methods of java.io.File to get a list of the directory contents and copy each file individually.
