Step-by-step explanation:
A file type can be defined as the standard used to store digital data such as pictures, texts, videos, and audios. They all have unique file extension which determines the type of software program (application) to be used for opening a particular file and accessing its data e.g pictures (jpeg, png), texts (txt, docx, rtf), videos (mp4, 3gp, avi), audios (mp3, acc).
Sometimes, computer users make the mistake of opening files with the wrong software application or program, this often leads to an error due to the incompatibility of the software application with the particular file.
