How to compress a file.

Summary:

File compression allows a person to minimize the space required to send/transmit a single or group of files. If you just have a few files, you may normally just send them as is…without compression. If the files are large (say 100mb+) or you have multiple files (fonts, images, etc…), you are advised to compress them into a single archive (ZIP) for the most efficient transmission.
