"Filename Extension"

What is a FILE EXTENSION or FILENAME EXTENSION?

According to Wikipedia – “a filename extension or file extension” is a suffix to the name of a computer file applied to indicate the encoding convention of its contents.” The file extension is limited to three characters only. I don’t know the reason behind it but maybe to make it shorter and easy to remember.

There are lots of filename extensions most of this are used in our daily use of the computer. Examples of this are .doc, .xls, and .ppt which are commonly seen on Microsoft Office programs. Other examples are .jpg, .bmp, and .png which are mostly used in pictures and graphic documents. And last example and most common of all is the .exe which can be run on all kinds of operating system.

There is also rare and uncommon filename extension which requires a certain program to open a certain file. One of this is the file extension ods. This document is called Open Document Spreadsheet which is created by programs like the open-source office suite or other similar programs. Users of this File extension ODS are mostly getting their data as bases for marketing research, statistics, and a like.
