• What is a File Type?: A file type, also known as a file format, defines how data is structured and stored within a file. It determines how the content is represented and how software applications interpret and handle that content.
• Importance of File Types: File types are essential for compatibility and efficient data processing. Different file types are optimized for specific types of data, and using the right format ensures that your files are correctly interpreted by the appropriate software.
• File Extensions and Formats: File extensions are typically three or four-letter codes appended to the end of a filename, indicating the file’s format. For instance, “.docx” indicates a Word document. Formats encompass a wider definition of how data is organized and stored.
