... Which brings us to the .module file.  The first part is a partial repeat of what we just did, but it's equally necessary.

• Open Notepad (or if it's already open, create a new file)
  • File » New
• Before you do any writing this time, immediately click File » Save
  • (This is for convenience purposes only, but it's well worth it.)
• Again, make sure you're saving it in the mymodule folder you already created
• Where it says Save as type: Text Documents (*.txt) change Text Documents (*.txt) to All Files (*.*)
• Where it says Encoding: ANSI change ANSI to Unicode
• Next to Filename: type mymodule.module (instead of what you typed last time, which was mymodule.info)
• Click Save

You should now have a file named mymodule.module, along with your mymodule.info file, both inside the same folder (whose name is mymodule). Here's a little "tree" diagram:

» My Desktop

⌊» mymodule

⌊» mymodule.info

⌊» mymodule.module

NOW, with the mymodule.module file still open, we can start writing the module itself.
