The Evolution of Icons in File Explorers: A Guide to Understanding their Purpose

In today's digital age, icons have become an integral part of our daily interactions with computer systems. Whether it's navigating through a file explorer or launching an application, icons play a crucial role in guiding us towards our goals. However, not all icons are created equal. In this article, we'll delve into the world of file explorers and explore the different types of icons that exist.

The Purpose of Icons

Icons are not just decorative elements; they serve a specific purpose. Their primary function is to guide users through a product or system in a smooth and effective manner. A good icon should provide important information in an understandable format, allowing users to quickly identify what each element represents. However, the effectiveness of an icon ultimately depends on the user's mental model, which can vary greatly from person to person.

Types of Icons

There are several types of icons that exist, each with its own unique characteristics. Reference icons, for example, use analogies or references to familiar objects to represent a concept. A classic example is the envelope icon used to represent email in Mac OS. This icon is straightforward and easy to understand, as it's based on the physical process of sending letters.

On the other hand, resemblance icons are direct representations of physical objects. These icons aim to accurately depict the object they're meant to represent, often with minimal embellishment. An example of a resemblance icon is the clock icon used in file explorers to represent time-related functions such as alarms.

Arbitrary Icons

Not all icons fit neatly into these categories. Arbitrary icons, also known as 'shapes with meanings that have to be learned,' are designs that don't have an obvious connection to the object they're meant to represent. These icons require users to learn their meaning through experience or context clues. The rocket icon used in Mac OS's Launchpad is a prime example of an arbitrary icon.

Why Different Icons?

So, why do different operating systems use different icons for similar functions? This can be attributed to the design philosophy and goals of each system. Windows, for instance, uses a white envelope icon to represent email, while Mac OS employs a stamp icon. Both designs are effective in their own right, but they cater to different user mental models.

In conclusion, icons play a vital role in our interactions with computer systems. Whether you're navigating through a file explorer or launching an application, icons help guide us towards our goals. By understanding the different types of icons and their purposes, we can better appreciate the design decisions behind them. In the world of file explorers, Mac OS's use of arbitrary and resemblance icons provides a unique user experience that sets it apart from other operating systems.
