Techopedia Explains File
In most operating systems, a file must have a unique name within a given file directory. However, while creating a filename, certain characters are considered illegal, and hence cannot be used. A filename is comprised of a name with a suffix, which is also known as a file extension. The file extension is two to four characters following the period in the complete filename. The file extension helps in identifying the type of file, file format and the attributes associated with the file.
