Organizing Files and Folders

A file is a collection of bytes that has a name and is stored in a computer
A file can store a “program” or “data”Organize files by storing them in foldersDisks contain folders that hold files
USB drivesCompact discs (CDs)Digital video discs (DVDs)Hard disks
Each drive is assigned a letter
Understanding the Need for Organizing Files
5
Windows (and all other operating systems) organizes folders and files in an hierarchy, or file system
Windows stores the folders and important files it needs to turn on the computer in its root directory
Folders stored within other folders are called subfolders
Understanding the Need for Organizing Files and Folders

Developing Strategies for Organizing Files

Developing Strategies for Organizing Files
8
Type of disk you use to store files determines how you organize those files
Storing files on removable media allows you to use simpler organization
The larger the medium, the more levels of folders you should use
You should have a “backup”, or duplicate copy, of all filesDefinitely all data filesAll program files that you don’t have available
in other forms (downloads, other media)
Exploring Files, Folders, and Libraries
9
Windows Explorer and the Computer window show the drives, folders, and files on your computerEach has a slightly different view
A folder window displays the files and subfolders in a folderDivided into two sections, called panes
Exploring Files, Folders, and Libraries
10
Using Libraries and Folders
11
When you open Windows Explorer, it shows the contents of the Windows built-in libraries by default
Libraries display similar types of files together, no matter where they are stored

Navigating to Your Data Files
13
The file path is a notation that indicates a file’s location on your computerG:\FM\Tutorial\Map.pngG: is the drive nameFM is the top-level folder on drive GTutorial is a subfolder in the FM folderMap.png is the full filename with the file
extension
Navigating to Your Data Files
14
Managing Folders and Files
15
Creating a folderIn the Navigation pane, click the drive or
folder in which you want to create a folderClick New folder on the toolbarType a name for the folder, and then press
the Enter key
Working with Folders and Files
16
Moving and Copying Files and FoldersMoving a file removes it from its current location and places it in a
new location you specifyCopying places the file in both locations
Naming and Renaming FilesFilenames provide important information about the file, including
its contents and purposeMain part of the filenameFile extension
A filename extension identifies file type and indicates program in which file was created
Deleting Files and FoldersRecycle Bin is an area on your hard disk that holds deleted files
until you remove them permanentlyFiles removed from a network drive do not go to the Recycle Bin!
Working with Compressed Files
17
Files stored in a compressed (zipped) folder take up less disk spaceAllows you to transfer files more quickly
Extracting a file creates an uncompressed copy of the file in a folder you specify, while the original file remains in the compressed folder
