 We will be using three functions to read plain text files,

+**open()** - returns a *File* object. Passing 'w' allows you to write into the

 **read()** or **write()** - reads from or writes to the file

 **close()** - closes the *File* object which allows Python to save the file
 
-### Opening Files with the open() Function
+Let's create our own files with python. Follow along with the Python
+interactive shell. Our code will work with any operating system.
+```python
+>> import os
+>> path = os.path.join('.', 'newFile.txt')  # Why does this work everytime?
+>> myFile = open(path, 'w')
+>> myFile.write('Hello [insert name]\n')
+>> myFile.close()

+>> print(helloFile.read())

+>> editFile = open(path, 'a') # if we just passed 'w', we would overwrite our data
+>> editFile = write('I like [insert food]')

+>> readFile = open(path)
+>> print(readFile.read())
+Hello [insertname]
+I like [insert food]

+# Summary
+Files and Folders are organized in a tree like structure. The path describes
+the location of the file or folder. The path can either be described with an
+absolute path or a relative path. The os.path module has a lot of functions we 
+can use to manipulate file paths.
+
+We can directly read and write plain text files. We first need to use the 
+**open()** function to give us a **File** object. With the File object, we are 
+able to **read()** from the file and **write()** to it. the **open()** function
+can be passed a 'read', 'write', or 'append' argument.
+
+Knowing how to manipulate files is useful because we are now able to store data
+after the program is finished and when the computer restarts. From this 
+foundation, we can learn how to manipulate whole files themselves; copying,
+deleting, renaming, moving them, and so forth in
