How to Zip and Unzip Files on the Mac Platform (Part 2)

This post is Part 2 of “How to Zip and Unzip Files.” To view Part 1 click here.

Q. What is a Zip file and why should I use it?

A. Zip is a common file format used for data compression and archiving files. The Zip format was first implemented way back in 1989 and in later years adopted by both Microsoft and Apple for incorporation into their operating systems.

In the early days of the internet, file transfer speeds and storage capacity were only a fraction of our current capabilities. Zipping Word or Excel files could reduce their size by up to 80% and the benefits were obvious. Even today, compressing files helps to dramatically speed transfers and reduce storage demands as well as ensure that files attached to an email message can still be opened successfully at their destination.

Benefits of zipping files:

  1. Collect a number of files into a single, easily managed archive file.
  2. Reduce the size of a file or group of files.
  3. Ensure the integrity of the files attached to an email message.

 

Q. My Apple computer does not have WinZip. How do I open a “zipped” file?

A. Zip compression is now a built-in feature of the Mac operating system, so the WinZip application is not required to zip or unzip.

To open or unzip a zip archive in Mac OS X Snow Leopard (10.6) and Lion (10.7):

  1. Double-click the zip archive file.
  2. The unzipped file or folder will be placed at the same folder level as the zipped file.

iPad and iPhone Tips — Part 1

ipadandiphoneMany Apple iPad and iPhone owners have jumped head first into using their shiny new devices without the need for a lot of instruction or reference material. We can attribute that to the intuitive ease of use of Apple’s latest version of iOS 5.1 — or, more likely, the fact that scarcely any documentation or a user manual is provided with either device! To help fill the gaps in users’ knowledge of their devices, here are some of our best iPad and iPhone tips and tricks in a friendly question and answer format.

Customize Your Home Screen and Dock

Q. Why are my app icons jiggling or bouncing? ipadhomescreenedit

A. Touching and holding an app icon until it jiggles will allow you to customize the appearance of your Home screen and Dock.

  1. Touch and hold any app icon until it jiggles.
  2. Rearrange apps by dragging their icons around.
  3. Move an icon to another screen by dragging it to the right edge until a new screen appears. You can have up to 11 Home screens!
  4. Drag an app to the Dock or drag an app from the Dock to your Home screen.
  5. You can also delete an app you’ve installed by clicking the “X” on the corner of the icon — but be warned that deleting an app from your device also deletes the documents and data created by that app!
  6. Press the Home button to exit out of editing mode and return to your Home screen.

Q. Why did my app end up in a new folder when I was arranging the app icons?

A. While you are customizing your Home screen, you can create folders by dragging an app icon directly on to another app.

  1. Drag an app icon directly on to another app to create a new folder containing both apps. The OS will suggest a folder name that you can tap to edit. Folders can hold up to 20 icons!
  2. Drag apps out of folders to the Home screen. When only one app is left in the folder, the folder disappears, leaving the app on the Home screen.
