read and write binary files (copying .jpg files)

[sooner]

I'm trying to read one image file and copy it to the same folder under another name.

Here's my c# Code..

private void copyBinaryFile()
        {
            string FILE_NAME = "c:\\testImage.psd";
            string FILE_NAME2 = "c:\\testImage2.psd";
 
            // Create the reader for data.
            FileStream fs = new FileStream(FILE_NAME, FileMode.Open, FileAccess.Read);
            FileStream fs2 = new FileStream(FILE_NAME2, FileMode.CreateNew);
            BinaryReader r = new BinaryReader(fs);
            BinaryWriter w = new BinaryWriter(fs2);     
 
            // Read data from File and Write to new file
 
                        // This is the part I'm sure isn't right...
            System.Byte bt = r.ReadBytes(fs.Length);
            w.Write(bt);
 
            r.Close();
            w.Close();
        }

I'm close. But I'm not sure how to loop through the binary reader and write the binary data to the new file? Eventually, I want to do this over a network and I don't know what the file types will be, so I have to read each file as binary and write it as binary to another folder.

How would I read the entire file and write the entire file as a new name?

Thanks
