Creating and Using Folders


Copyright © 2014 Pearson Educa=on, Inc. Publishing as Pren=ce Hall Visualizing Technology

Using Windows or OS X help, research the Public folder on your computer. What purpose does it serve? What types of files can be stored in it? Who has access to those files? What restrictions are there on their access?


1.  Discuss and learn the file naming rules 2.  Discuss and learn the file naming limitations 3.  Discuss file extensions and understand how the

extensions identify the file type 4.  Explore file properties and how they can be used

to sort and search for files Key Terms §  File extension §  File name §  File property

What’s in a Name?


§  File names contain name and extension §  Can be up to 260 characters long §  May include spaces and special

characters §  Illegal characters: \ / ? : * ” > < |

File Extensions


File Properties

§  Proper=es used to organize, sort, and find files more easily

§  Automa=cally created: §  File type §  Size §  Date

§  Title and author can be added or edited by the user


OS X File Properties


Info Pane

We discussed how to add properties to a file, but how would you remove them? Which properties can you remove? Use Windows Help and Support to find the answers.



1.  Discuss the importance of backing up files 2.  Discuss backup storage options 3.  Discuss the pros and cons of backup storage types 4.  Discuss backup storage software options 5.  Discuss online backup storage options Key Term §  Back up

Back It Up


Back Up Your Files

§  Copying files to another loca=on

§  Backup storage op=ons: §  Internal hard drives §  External hard drives §  Op=cal drives §  Flash drives §  Networks

§  Backup u=li=es make it easy §  Online backup services


Windows Backup Utility


OS X Time Machine


Backup Options

§  External hard drives: §  Inexpensive usually less than $100

§  Cloud: §  Free personal

storage –1 or 2 GB §  Unlimited storage

for about $5 –10 per month


Research two online backup sites and investigate their cost, reliability, storage size, and features. Create a table to compare what you found.



1.  Define file compression and its advantages 2.  Discuss the different types of file compression 3.  Discuss how Windows can create and extract ZIP

archives Key Terms §  Algorithm §  Compression §  Lossless compression §  Lossy compression

Shrink It


File Compression

§  Process of making files smaller: §  Conserves disk space §  Easier to transfer

§  Types of file compression §  Lossy §  Lossless

§  Windows can compress and decompress files using ZIP format


File Compression

Lossy §  Usually for image,

photo, video, and multimedia files

§  Substantial amount of data can be discarded before the result is sufficiently degraded to be noticed

Lossless §  Usually for files that

contain text and numbers

§  Takes advantage of redundant information

§  Files can be decompressed with NO loss of data


§  Windows can open and browse files in a ZIP archive

§  Popular file compression programs: §  7-ZIP § WinRAR § WinZip §  Stuffit

File Compression


An MP3 file is a compressed audio file that uses a lossy compression algorithm. Many audiophiles say they can hear a difference in sound quality. Use the Internet to research ways to improve the quality of MP3 files.



1.  Discuss how to use advanced search options to find files using the Windows search feature

2.  Define Boolean operators and how they can be used to create search filters

3.  Discuss how Windows maintains an index of the files located on your computer

Key Terms §  Algorithm §  Boolean operators §  Index

It’s Always the Last Place You Look


Search Options File Explorer


Windows 8 Search


Spotlight in Mac OS X


Search Options Boolean Logic

§ Created in 19th-century § George Boole

§  Boolean operators: §  AND §  OR §  NOT

§ Used to create search filters in Windows, most databases, and Web searches


Use Windows Help and Support or the Internet to research natural language search. What is it and how does it change the way you can search your computer?



1.  Define a default program 2.  Discuss how default programs are associated with

certain programs 3.  Learn how to change or set the default program

associated with a file type Key Term §  Default program

That’s Not the Program I Want to Open This File Type


Default Programs

§  Application that is associated with a file §  Allows you to open, view, and edit the file §  Some file types open in multiple applications


Default Programs


Managing File Types


Use the Default Programs control panel or Finder on your computer to complete this section of the project. What program is currently associated with MP3 files? What other files types can this program open by default? What other programs are installed on your computer that can open MP3 files by default?
