I wont copy txt file,like in the lynda java Esential course,but not work : I copied all this code from Lynda Java Essential Treining 2016 Episode 70.I run 
aplication and i see this problem:

java.io.FileNotFoundException: files\copytest.txt (The system can not find the path specified)
	at java.io.FileInputStream.open0(Native Method)
	at java.io.FileInputStream.open(Unknown Source)
	at java.io.FileInputStream.<init>(Unknown Source)
	at java.io.FileInputStream.<init>(Unknown Source)
	at java.io.FileReader.<init>(Unknown Source)
	at de.exercise.copyfile.Copyfile.main(Copyfile.java:108)


This is the code:
        
        String sourceFile="files/copytest.txt";
		String targetFile="files/copied.txt";
		
		try(
				FileReader fReader=new FileReader(sourceFile);
				BufferedReader bReader=new BufferedReader(fReader);
				FileWriter writer=new FileWriter(targetFile)
				
				)
		
		{
			while(true){
				
				String line=bReader.readLine();
				if(line==null){
					break;
				}
				else{
					writer.write("jarek"+"\n");
				}
			}
			System.out.println("File copied succesfull!");
		}catch(Exception e){
			e.printStackTrace();
		}
	}
I copy new code,to read from txt file:

    File file = new File("files/copytest.txt");
	      Scanner in = null;
		try {
			in = new Scanner(file);
			 String zdanie = in.nextLine();
		      System.out.println(zdanie);
		} catch (FileNotFoundException e1) {
			e1.printStackTrace();
		}

But this is the same problem:
java.io.FileNotFoundException: files\copytest.txt (The system can not find the path specified)
