File storage refers to the method of saving digital files on a storage device, such as a hard drive, solid-state drive, or cloud service. This system allows users to organize, access, and manage their files efficiently. Common file types include documents, images, videos, and software applications, which can be stored in various formats like PDF, JPEG, or MP4. In file storage, data is typically organized in a hierarchical structure, using folders and subfolders to categorize files. This organization helps users locate and retrieve their files quickly. Additionally, file storage solutions often include features like backup options and security measures to protect data from loss or unauthorized access.
