Here is a code that checks the file existence and find the length of the file in bytes.

import java.io.*;
class FileExists 
{
    public static void main(String[] args) 
    {
        File f=new File("c:/data.txt");
        if(f.exists()){
          long s=f.length();
             System.out.println(s);
        }
    }
}
