You’ve just finished download zip file, and now you have a cryptic “.zip” file sitting on your hard drive. You’ve heard of Zip and WinZip, but no one has ever explained it to you. What do you do now?
Answer: ‘Zipping’ and ‘unzipping’ is a file management technique for packaging multiple files into a single small bundle. Zipping and unzipping are very popular for emailing file attachments, downloading, and FTP. Let’s look at zipping in its smaller parts:
Question 1: What is a Zip File?
Answer: A Zip file is sometimes called an “archive” file. The Zip file itself is really just a container… it holds the real files inside it. The purpose behind the Zip file is transportation and storage. The Zip file acts like a ziploc sandwich bag – it holds contents inside for easy transporting and storage. This makes Zip files (and their counterpart Rar files) very valuable to file sharers and downloaders.
Question 2: How Do Zip Files Work?
Answer: A Zip file achieves three things:
1. It bundles one or more files into a single container file.
2. It compresses (archives) its contents to be as much as 90% smaller size.
3. It can provide an optional password padlock on its contents.
Question 3: Is ‘Zip’ the same as ‘WinZip’?
Answer: Although many people confuse the two, they are technically different.
1. “Zip” is the generic file format of a compressed archive.
2. “WinZip”, like “WinRAR”, “7zip” or “PKZip”, is specialty software that creates and manages Zip files.
