Storage Media



A computer

file

is a named collection of

stored data



An

executable file

contains the

instructions that tell a computer how to

perform a specific task



A

Files and Folders



Windows organizes folders and files in a

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

(3)

Hierarchy / Directory Tree

Organizing Files



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



My Documents folder



You should have a backup, or duplicate

copy, of important files

4 Well Organized Files

File Path



The file path is a notation that indicates a

file’s location on your computer

F:\FM\Tutorial\Holiday.bmp

F: is the drive name

FM is the top-level folder on drive F Tutorial is a subfolder in the FM folder Holiday.bmp is the full filename with the file

extension

What is a folder?

 A folder is basically a box or container in which

files are held.

 Folders are used to group together related files

 Folders are somewhat like drawers in a file cabinet.

 On a computer, a folder is used to contain all like files together, such as music in one folder, documents in another, and so on.

 Thus, organizing files in this manner, files can readily be found without sifting through a plethora of files to find the one you want.

(5)

What is a subfolder?

 Subfolders are simply folders which are placed

within another folder.

 In theory, subfolders are similar to folders within folders in a filing cabinet.

 The cabinet is the main folder which holds all the folders, or files, but each folder is a subfolder and is responsible for storing specific types of files.

 You can create subfolders within subfolders.

File Names

 A file name is made up of two parts:

the name of the file the file extension

 You may name a file anything you wish, but you should probably name a file something you are likely to remember later.

 Use only letters and numbers in your file names -- Special characters like “*", "/", "&", must be avoided in the file name.

 Try to avoid spaces in file names when sending to others.

File Names



The second part of a file name is the

extension.



In the file Holiday.bmp,

’Holiday’ is the file name ’bmp’ is the extension.



A period always separates the two.



The extension identifies what kind of a file

you have.

(6)

6 8.3 vs Long File Names



Back in the old days, file names could only

have a name up to 8 characters long and

a 3 character file extension after the period



Long file names were created so you

could have more descriptive names.



Sometimes the long file name is translated

to a 8.3 file name by truncation



EG: file “TextFile.Mine.doc” becomes

TEXTFI~1.DOC

the correct program by clicking on a data

Create a new folder

Open Windows Explorer

1. You can create a new folder by right-clicking a blank area in a folder window or on the desktop, pointing to New, and then clicking Folder.

2. You can also create a new folder under FILE on the main menu (Alt to show menu), then NEW, then FOLDER

Desktop Shortcut

 Easiest way to create a desktop shortcut is to browse to the file you wish to create a shortcut for | right click | Send To | Desktop (create Shortcut)

 Shortcuts are NOT the original file, but a pointer to a file. Indicated by a little arrow

 Note: Deleting a shortcut does NOT delete the file.

Copying vs. Moving

 When using the drag-and-drop method, you might notice that sometimes the file or folder is copied and at other times it is moved. Why?

 If you are dragging an item between folders that are on the same hard drive, then the items are movedso two copies of the same file or folder aren't created on the same hard drive.

 If you drag the item to a folder that's on a different hard driveor to removable media like a CD or flash drive, then the item is copied. That way the file or folder isn't removed from its original location.

8 Working with Compressed

Files



Files stored in a compressed (zipped)

folder take up less disk space

Allows you to transfer files and directory structures as one file

Extracting a file creates an uncompressed copy of the file in a folder you specify, while the original file remains in the compressed folder



Created the same way as creating a new

folder, except you select “Compressed

(zipped) Folder”
