What is a Computer File Extension ?

A computer file extension is a set of characters that are added to the end of a file name, after a period (.). It is used to identify the type of file and what software program can open or execute it. File extensions are used by the operating system to determine which program should be used to open or execute the file. Some examples of file extensions include .txt for a text file, .docx for a Microsoft Word document, .jpg for a JPEG image, and .exe for an executable file.

File extensions are also used to indicate the file format, which determines how the data in the file is structured and encoded. Some file formats are open and documented, like the .txt or .html, which can be opened and read by any text editor, while some are proprietary and can only be opened by certain software like .docx, .xlsx, .pptx and so on.

File extensions also help users to quickly identify the type of file and the purpose of the file. For example, a file with the .pdf extension is likely to be a Portable Document Format file, which is commonly used for electronic documents that are meant to be read-only. Similarly, a file with the .mp3 extension is likely to be an audio file, which can be played by a media player.

It’s worth noting that some file extensions are hidden on certain operating systems, but users can easily configure their computer settings to show or hide the file extensions.
