Path

How do your find a file - you have to find a pathway to it.

What is a File Path?

A file path is a string of text that describes the location of a file or folder within a file system. It shows the “route” you need to take, starting from a specific point (such as the root directory or current directory), to get to a particular file or folder.

Key Points

• File System: Computers organize files and folders (directories) in a structure called a file system, which is often compared to a tree with branches.
• Path: A path is like giving directions to a destination in this tree. It tells the system (and you) exactly where a file or folder is located.

Types of File Paths

1. Absolute Path

   • Shows the full, complete address to the file/folder, starting from the root directory.
   • Example (Windows):

     C:\Users\Alice\Documents\Report.docx
     

   • Example (Linux/macOS):

     /home/alice/Documents/report.txt
     

2. Relative Path

   • Shows the address relative to your current directory.
   • Example:
     If you’re already in C:\Users\Alice, a relative path to the document above would be:

     Documents\Report.docx
     

Path Separators

• Windows uses a backslash (\)
• Linux/macOS use a forward slash (/)

Components of a Path

• Directories/Folders: Containers that can store files and other folders.
• Filename: The name of the file you want to access (which may also include its extension, like .txt, .docx).

Example:
/Users/beth/photos/vacation.jpg
Here, Users, beth, and photos are directories, and vacation.jpg is the file.

Visual Example

Given a structure like:

/
 └── home/
       └── alice/
               ├── Documents/
               │      └── notes.txt
               └── Pictures/
                       └── photo.jpg

• Absolute path to notes.txt: /home/alice/Documents/notes.txt
• Relative path from alice directory to photo.jpg: Pictures/photo.jpg

Summary

A file path tells you (and your computer) precisely where a file lives in your file system. It’s like an address for a file!
