When you no longer need a file, you can remove it from your computer to save space and
to keep your computer from getting cluttered with unwanted files. To delete a file, open the
folder that contains the file, and then select the file. Press Delete on your keyboard and then,
in the Delete File dialog box, click
Yes 
When you delete a file, it’s temporarily stored in the Recycle Bin. Think of the Recycle Bin as a
safety net that allows you to recover files or folders that you might have accidentally deleted.
Occasionally, you should empty the Recycle Bin to reclaim all of the hard disk space being
used by your unwanted files.
• How do you delete files permanently?
Opening an Existing File
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 text file will open in your word-processing program.
That’s not always the case, though. Double-clicking a word file, for example, will usually open
the Microsoft Word program.
To open a file:
• Double click the file, the file will open in the program
• Right-click the file, click Open with, and then click the name of the program that
you want to use.
