To work with files you must first have some! Playing around with files already on the hard disk might get us all in trouble. So you will first create some files. Then you can play with them!
You learned to open an application from the Start menu in Windows Basics. In this section you will learn another method.
The application Notepad is a plain text editor. This means that you can create documents that contain only text - no graphics.
It also means that you can't get fancy. No tables, frames, or other fancy features. So why bother??
Every word processor out there can read such a plain text document, when they don't read each other's file formats well at all! What Notepad creates is just fine for writing simple memos, lists, or quick notes and is widely used for writing programming code. So Notepad is well worth meeting.
Notepad opens with a new blank document ready for your typing. Many applications behave this way. Others offer you the option first of opening an existing document or picking a template for a new document.
The cursor is the shape that shows where the text you type will go. Different programs use somewhat different shapes. A vertical bar of some type is the most common. Do you see the cursor in the illustration of Notepad? It is the vertical bar at the end of the typing.
Undo in Notepad: You can only undo the last action in Notepad. Clicking somewhere can be an action!

What you will learn: | to open an application from File Explorer to create a new document to save a document to close an application |
Start with:
To use this method to open an application, you need to know:
a. the name of the file that starts the application
b. what folder the file is in
Problem:
Filenames do not show the extensions
Most installations of
Windows do not show the file name extensions by default. Anyone who works with many types of documents will understand why hiding the extension is a bad idea!
Solution: Change the setting -On the View ribbon tab in the Show/hide section, check the box 'File name extensions' to show the extensions.
Since this document has not been saved before, you will see the Save As dialog box. For most applications the Save In text box shows the folder last used to save something, even if it was by a different program. Others programs have a default folder for saving files.
Remember - spaces are important in a path, too!
The title bar of Notepad changes to include the new name, with a txt extension automatically added. Most applications have a
default extension to add to a filename if you don't type it in yourself.
To see what extensions an application uses on its saved files, click on the down arrow in the 'Save as type' box. In an Open dialog box, on the other hand, this list will show what extensions the program can open. But it may not be able to save in those types. For example, Microsoft Word can open Lotus Word Pro documents (extension lwp) but cannot save in that format. It's a one-way translation.
If you made changes to your document since the last time you saved it, a dialog will appear that asks if you want to save the document. Only you know if you need to save those changes.
