Most common files are made up of a name and an extension. There are many types of computer files used by people to store data or information.
Types of computer files and their uses
A computer file is a storage unit that is held on a computer’s operating system. Different types of files in computers have different uses, as explored below.
Types of files for documents
Different text files are normally used in places of work and educational institutions. Below is a look at these types of computer files with examples.
Word document (DOC and DOCX)
Microsoft created Word files and revolutionised sending and receiving documents. DOC and DOCX documents are the standard file types for documents in the modern era.
Word documents are used for typing documents, e.g., letters, essays, and homework. Did you know Microsoft Word was originally developed by Charles Simonyi and Richard Brodie in 1983?
Portable document format (PDF)
PDF files are among the most commonly used text files today. They normally end with .pdf and are mainly meant for viewing rather than editing.
One of the reasons why PDF documents are popular is because they preserve document formatting, making them more shareable. They look the same on any device. Examples are newsletters and magazines.
Hypertext markup language (HTML and HTM)
HTML files are text-only documents containing highly interactive content. They are designed for digital viewing only.
You can view HTML or HTM files on-screen but cannot in printed format. It is possible to convert an MS Word doc into HTML format.

Types of files for images
Did you know there are different types of image and picture files? Below is an exploration of these types of computer files and examples.
Joint Photographic Experts Group (JPEG/ JPG)
ISO/IEC Joint Photographic Experts Group created JPEG or JPG filed. These are graphic image files compressed with discrete cosine transform using the standard developed by the developer.
The higher the quality setting, the larger the file size and the less compression is applied. Although JPEG/ JPG files are common, they are not always suitable for images.
Graphics Interchange Format (GIF)
People love GIFs because they are quick to create and do not need too much technical know-how to create. Besides, they tend to go viral across social media platforms, as do memes.
GIFs are commonly used on the Web to display graphics and logos. They support basic animations and are designed for relatively basic images that appear on the internet.
Portable Networks Graphic (PNG)
Portable Network Graphics is a file format used for compressing images without losing data. PNGs are popularly used in graphics in the present-day era.
It is worth noting that PNGs occupy more space than JPEGs, and images cannot be animated. The top advantage of PNG files is they do not become blurry or distorted.
Scalable Vector Graphics (SVG)
SVGs are most commonly used in website design. SVG is a text-based graphics language used to illustrate images with text, vector shapes, and embedded raster graphics.
These files are lightweight and present high-quality graphics in print and on the Web. They also support scripting and animation.
Tagged Image File Format (TIFF or TIF)
TIFF files are mainly used by graphic artists, photographers, and the publishing industry. When it comes to images, the format uses the Lempel-Ziv-Welch lossless compression method.
TIFF images are significantly larger than JPEGs, so they consume more space. They can store multiple layered images. TIFF has more features and capabilities than other formats explored above.

An audio format is a file format for storing digital audio data on a computer. These are sound files that play a sound when opened. An example of this file format is a song without visuals, and below are the different types of audio files.
MPEG Layer Audio 3 (MP3)
MPEG Layer Audio 3 (MP3) is commonly used to compress and store audio files. The MP3 digital audio format is used to compress a sound sequence to a smaller file while preserving the original audio quality.
Waveform Audio File (WAV)
IBM and Microsoft developed Waveform Audio File (WAV). The format does not apply compression to the bitstream.
Instead, it stores the audio recordings with different sampling rates and bitrates. It is one of the standard formats for audio CDs.
MPEG 4 Audio (M4A)
Apple developed the MPEG 4 Audio (M4A) format. It stores audio content types, e.g., podcasts, songs, and audiobooks.
M4A supports audio, video, and other data encoded using various codecs. These files have .mp4 extensions.
Types of files for videos
Video file formats are used to store digital video data on computer systems. Check out the types of files for videos below.
Audio Video Interleave (AVI)
Microsoft introduced the Audio Video Interleave (AVI) format in 1992. AVI files normally contain audio and video data. AVI is a large file type that can occupy plenty of space on your computer or cloud system.
Flash Video Format (FLV)
Adobe Systems developed Flash Video Format (FLV). The files have a .flv extension and are normally used to communicate audio and video content over the internet.
Moving Picture Experts Group Layer Four (MP4)
MP4 is a digital multimedia container format. It is mainly used to store video and audio data, but it can also be used to store other data, including subtitles and still images. The MP4 format is normally used for downloading and streaming videos from the internet.
Advanced Video Coding, High Definition (AVCHD)
AVCHD is the acronym for Advanced Video Coding, High Definition. It is a file-based format for the digital recording and playback of high-definition video. It was developed for recording high-definition video to media, e.g., hard disk drives, memory cards, and recordable DVD media.
QuickTime Movie File (MOV)
MOV files have the .mov file extension suffix. Apple launched the MOV file format in 1998. These files implement the Apple QuickTime Movies encoding requirements and data. This format is commonly used in Apple devices.
