Folder hierarchy and paths in Intro to Computing - Flowchart & Logic Diagram

Process Overview

A folder hierarchy is like a family tree for your computer files. It shows how folders (also called directories) are organized inside one another. Paths tell you exactly where a file or folder lives in this tree, like an address.

Is path absolute?

↓

Start at root folder

↓

Read next folder name

↓

Go up one folder

↓

Read next folder name

This flowchart shows how a computer reads a folder path step-by-step to find the exact location of a file or folder. It checks if the path is absolute or relative, then moves through each folder name, handling special names like '..' to go up one level.

Step-by-Step Trace - 7 Steps

Step 1: Check if the path is absolute (starts with root).

Step 2: Start at the root folder '/' because path is absolute.

Step 3: Read next folder name 'home'.

Step 4: Read next folder name 'user'.

Step 5: Read next folder name 'docs'.

Step 6: Read next folder name 'file.txt' (file).

Step 7: No more folder names to read, end process.

This diagram shows a folder hierarchy tree. Each folder is inside the one above it. The file 'file.txt' is inside the 'docs' folder, which is inside 'user', then 'home', then root.

Flowchart Quiz - 3 Questions

What does an absolute path always start with?

A The parent folder symbol '..'

B The current folder symbol '.'

C The root folder symbol '/'

D A file name

Key Result

Folder paths guide the computer step-by-step through a folder hierarchy to find files, starting either from the root or current folder.
