This flowchart shows the steps a computer takes when opening a file: starting from user action, checking the file extension, deciding if it is known, finding the associated program, and opening the file or showing an error.

Step-by-Step Trace - 5 Steps

Step 1: User double-clicks a file named 'photo.jpg'.

Step 2: System checks the file extension '.jpg'.

Step 3: System asks: Is '.jpg' a known extension?

Step 4: Since '.jpg' is known, system finds the associated program (e.g., Photo Viewer).

Step 5: System opens 'photo.jpg' with Photo Viewer.

Diagram
