A "File Type" refers to the format in which data is stored on a computer or digital device. Each file type is identified by its extension, which is the suffix at the end of the file name, such as .txt for text files or .jpg for image files. Different file types determine how the data can be used, opened, or edited by software applications. File types are essential for organizing and managing digital information. They help users understand the kind of content contained within a file and which programs can open it. For example, a .pdf file is typically used for documents that need to maintain their formatting, while a .mp3 file is used for audio content.
