13. • When you create a document in a program, you make a
file.
• Your file is stored somewhere on your computer or storage
device.
• Every file must have a distinctive name.
• Files can be stored in folders.
14. Copying and Moving Files and
Folders
Most people copy and move files using a method called drag and
drop.
Start by opening the folder that contains the file or folder you want to
move.
Then, open the folder where you want to move it to in a different
window. Position the windows side by side on the desktop so that you
can see the contents of both.
Next, drag the file or folder from the first folder to the second folder.
15. More about files
The most common way to create new files is by using
a program.
To delete a file, select the file, press Delete Key. In
the Delete File dialog box, click Yes.
To open a file, double-click it. The file will usually
open in the program that you used to create or
change it. For example, a Word file will open in
Microsoft Word program.
