What is the primary function of a paper shredder?

The primary function of a paper shredder is to act as a mechanical device specifically designed to cut paper into small pieces, effectively destroying documents. This process not only helps to safeguard sensitive information by preventing unauthorized access but also supports secure disposal practices for confidential materials. Paper shredders come in various sizes and capacities, designed to handle different volumes of paper, and they are commonly used in both personal and professional settings to enhance data security.

When considering the other options, organizing documents pertains to arranging and categorizing files rather than destruction, printing involves creating physical copies of documents which is unrelated to shredding, and software for document storage refers to digital solutions for maintaining files rather than physical document destruction. Thus, option A accurately represents the key purpose of a paper shredder.
