Absolute Path vs. Relative Path: Know the Difference

By Shumaila Saeed || Published on February 22, 2024

An Absolute Path is a complete path from the root element to the desired directory or file, while a Relative Path describes the location relative to the current directory.

Absolute Path vs. Relative Path

Key Differences

An Absolute Path is a complete and direct address to a file or folder in a file system, starting from the root directory. It remains constant, regardless of the current working directory. In contrast, a Relative Path specifies a location starting from the current directory and is flexible based on the user's current position in the file system.

Feb 22, 2024

Absolute Paths are not portable across different systems as they include a full address that may vary between systems. Relative Paths are more portable as they depend on the current directory, making them useful in shared environments or scripts that need to run on different machines.

Feb 22, 2024

Generally, Absolute Paths are longer, providing the complete directory path. Relative Paths are usually shorter, using only the necessary portion from the current directory, which can simplify file referencing in complex systems.

Feb 22, 2024

When file system structures change, Absolute Paths need to be updated to reflect these changes, making them less adaptable. Relative Paths can remain unchanged if the relative structure is maintained, offering more flexibility.

Feb 22, 2024

In Unix/Linux, an Absolute Path starts with '/', like "/home/user/documents". A Relative Path might be "documents/project.txt", assuming the current directory is "/home/user".

Absolute Path and Relative Path Definitions

Absolute Path

Unique to each operating system's file structure.

/etc/apache2/httpd.conf (on a Unix/Linux system)

Jan 18, 2024

Relative Path

Maintains validity if the relative structure is constant.

Jan 18, 2024

Absolute Path

Remains constant regardless of current directory.

C:\Program Files\MyApp\config.txt

Jan 18, 2024

Relative Path

Indicates location relative to where we currently are in the file system.
