Delete a File
When you no longer need a file, you can delete it. This helps to prevent your hard drive from becoming cluttered with unnecessary files. You should ensure that you delete only those documents that you have created or that have been given to you by someone else. Do not delete any of the OS X system files or any files associated with your applications, or your computer may behave erratically, or even crash.
