Document files are digital files that contain text, images, or other data, making them easy to create, edit, and share. Common types of document files include Microsoft Word documents, PDFs, and Google Docs. These files are widely used for writing reports, creating resumes, and sharing information in a professional or personal context. One of the main advantages of document files is their versatility. They can be formatted in various ways, allowing users to customize the appearance of their content. Additionally, many document files support collaboration, enabling multiple people to work on the same file simultaneously, which is especially useful in team projects or academic settings.
