TIP
When reading filenames out loud, the period in the extension is usually pronounced "dot." So myfile.txt would be pronounced "myfile dot text" or "myfile dot tee ex tee."
User's Guide - Files, Folders and Paths
An extension is the part of a filename that is used to indicate what kind or "type" of data is contained within a file.
A file extension consists of a period (.) followed by one or more characters at the end of a filename. Windows uses the file extension to determine what kind of information is contained in a file. For example, in the filename myfile.txt, .txt is the file extension that identifies myfile.txt as a text file.
