Description: A regular file is a standard file type in operating systems that contains data, as opposed to directories or special files. These files can store text, images, audio, video, and other types of information. In most file systems, regular files are fundamental, as they represent the majority of the data that users and applications handle. They are characterized by having a variable size and can be read or written by users, depending on the permissions set. Regular files differ from other file types, such as directories, which act as containers for organizing other files, and special files, which are used by the operating system to interact with hardware or perform specific functions. In certain security-enhanced systems, regular files can have security labels that determine which processes can access them and in what manner. This is crucial for protecting the integrity and confidentiality of the data stored in these files, ensuring that only authorized users and processes can interact with them.
