List of File Types/ File extensions Part 2
Part 2
This list of file types sets out to answer the common question "What is a file of type .x?" or "What is that file extension for?"A file type is denoted by those letters that follow the last dot in a file name. These letters denote the type of file, and are also commonly known as a file extension. On Windows PCs the file extension may be hidden by Windows, but is still part of the file name.
This list of file types contains a list of file extensions together with a brief description of the type of file that the extension is associated with.
