File Handling

• Before you do anything with a file you need to open it
• To open a file, use an open command ( 'open()' ) and assign it to a variable
• What is the name of the file that this code will open?

  file.txt

  
• Some programming languages have separate modes for reading and writing - so they require you to say which mode you are in
• You can create a new text file using the newFile command

  
• After you have created a file , you still need to open the file using the open() command
• After you have opened a file you can read or write to it
• You can use the writeLine() command to write lines of text to a file
• The writeLine() command will always write to the end of the text file
