The Documents file is much more than a simple category in your Start menu. Here you'll find the My Documents folder as well as a lengthy list of recently opened documents. Windows uses My Documents as the default storage folder for Windows.
Periodically go through your My Documents folder and delete files you no longer need. Open the folder by clicking o­n your desktop icon. If you don't have a shortcut o­n your desktop, follow these steps.

1.  Double-click My Computer.
2.  Double-click the C: drive.
3.  Open the My Documents folder.

Remember to empty the Recycle Bin when you're finished deleting your files.

Another feature in Documents is a list of every document you've recently modified or saved. To clear your Documents history, follow these steps.

1.  Right-click the taskbar.
2.  Select Properties.
3.  Choose the Start Menu Programs tab.
4.  Click the Clear button.
