File handling is one of the primary functions of a computer system. Based on the type of data that needs to be stored, several types of file formats are available. Each file format occupies certain storage space. An image file with good quality occupies around 1 MB and a video file needs to store 25 frames per second occupying large storage space. Thus, compression methods are used to reduce the size of the files. Compression is also helpful in reducing the download time of image, audio and video from the internet. In this chapter, different types of files formats and compression methods are explained.
