Normally, we use Ctrl or Shift to choose multiple files or folders in Windows 7 or Vista. But in windows 7 we have got the new feature of choosing multiple files and folders by just using mouse, by enabling this feature you can see check boxes above the icons of your files and folders using which you can mark multiple files and folders by just using your mouse. By default this feature is disabled so most users might not know this option

1. Go to Start and click on Control Panel
2. Then click on the View by Large Icons
3. Next click on the Folder Options
4. From folder option window click on the View tab
5. Under Advanced Settings insert a check mark next to Use check boxes to choose items
6. Then click on Apply and OK to save the changes
7. Now you should have check boxes available to mark multiple items

After marking files or folders, you can perform many common tasks, such as copying, deleting, renaming, printing, and compressing. Simply right click on the marked items, and then click the appropriate choice
