DIFFERENT FILE FORMATS
You must have observed that whatever we do on a computer is saved as a file. But every file stores
a different type of data, like a Word file stores text, a video file contains multimedia, an audio file
contains audio and a picture file stores pictures. So, how does a computer differentiate between
different types of files? The file type is also called the file format.
So, all these files contain different types of data and are saved in a specific format. The file format
can be determined by the file extension. A file extension is a group of three or more characters
used to identify the type of a file. It helps an operating system recognise the different types of
files.
The file formats of different types of files depend upon the software used for creating those
files. Software puts a file extension after the file name to specify its format. Some of the most
commonly used file extension, or file formats are:
JPEG: It stands for Joint Photographic Experts Group. It is used to store images. The file
extension of a image file can be .jpeg, .jpg, or .jpe.
MP4: An MP4 file is used to store multimedia content. It can contain audio, video, movies,
and still images. A file with an MP4 extension is an MPEG-4 video file.
MP3: It is an audio file format that is used to store music files. MP3 stands for Moving
Pictures Expert Group. The file extension of an audio file is .mp3.
DOCX: It is used to save Word documents. This document stores images, text, pictures, and
tables. The file extension of the Word file is .docx.
XLSX: An XLSX file is used to store spreadsheets in Microsoft Excel. This file format stores
tables in the form of rows and columns, as well as images, charts, pictures, formulas, and
more. The extension of an Excel file is .xlsx.
PPTX: It is used to store presentations and is used in Microsoft PowerPoint. It saves the data
in the form of slides. The extension of the presentation file is .pptx.

Data on a computer can be arranged in the form of files or folders.
Windows Explorer helps us to organise and manage files and folders.
When we move a file or folder from one drive to another, the original file or folder will
be removed from the original location and moved to a new location.
Sorting means arranging the files on the computer.
A wildcard is a special character that is used to represent one or more characters.
We can use multiple applications simultaneously in Windows.
File extensions help an operating system recognise the different types of files.
