What is the main purpose of creating folders on a computer?

Creating folders on a computer serves the primary function of keeping job files organized. By using folders, individuals can categorize and store related files in a structured manner, which enhances efficiency when searching for and accessing specific documents. Organization is crucial, especially in graphic design, where multiple projects may contain numerous assets like images, layouts, and revisions. An organized file system allows designers to locate resources quickly, maintain workflow continuity, and reduce the likelihood of misplaced files.

The other options, while they address various aspects of computer use, do not pertain directly to the primary purpose of folders. Deleting unnecessary files, increasing computer speed, and installing new software are all important tasks in managing a computer's overall performance and storage; however, they do not capture the essential role that folders play in file organization.
