How to archive and compress files and folders

An archive is a group of files or folders which have been crunched or compressed and bundled together into a single file in such a way that the individual files may be recovered intact. They are used to manage files and folders that contain information you want to keep but that you rarely access and aren’t currently using. They are compressed to save disk space and transfer time over Internet.
