Course 1: Computer Literacy / Unit 3: Operating Systems & File Management / Lesson
2: File Paths, File Extensions, and Disk Storage

## Before we begin

What does a file extension (like .docx, .pdf, .png) tell the operating system?

Record your initial thinking. Be ready to explain your reasoning and revisit your
response after the lesson.

## Laptop Ticket

intro, body, conclusion): Why do you think files have endings like .pdf or .png 
instead of the computer just figuring out what each file is? Explain what could 
go wrong if they didn't.
