Everything you need to know about computer file

A file is an object on a computer that stores data, information, settings, or commands used by a computer program. In a GUI, such as Microsoft Windows, files are displayed as icons that refer to the program that opens the file.

How is a file created?
The file is created using computer software. For example, to create a text file, you would use a text editor, to create an image file, to use an image editor, and to create a document, you would use a word processor.

Where is a file stored?
Computer files are stored on a disk drive, disk (such as a DVD), and floppy disk.

On a Microsoft Windows computer, users can view, manage, and organize their files using Windows Explorer, and Apple users can use Finder. See our file system definition for more information about file management.

Different types of files
JPEG is the most common format used by digital cameras and images on the web. This file format is based on lossless compression, which means that it retains visible information to the viewer and removes data that cannot be perceived by the human eye. The popularity of a JPEG file stems from the fact that it is lightweight while maintaining good quality for digital use.

PNG is a high-quality file format used for images. This file type is based on lossless compression, which means it supports high-quality images for online use while retaining the original color and sharpness of the image.

A GIF file is a bitmap image format, which means that the graphics are made up of many tiny parts called pixels, just like the JPEG and PNG file formats. This file type is based on LZW (Lempel-Ziv-Welch), a special form of the lossless data compression algorithm.

PDF file format is used for online documents and printing purposes. It was created by Adobe to display files in the same format, no matter what device they are viewed on or what software they are opened with. 

SVG is a format commonly used to store and display vectors.

MP4 is a multimedia container format that is just an imaginary term for most of the videos we consume on the Internet. This file can contain video, audio and subtitles.
