When you delete a file, depending on your operating system and your settings, the file may be transferred to your trash or recycle bin. This "holding area" essentially protects you from yourself-if you accidentally delete a file, you can easily restore it. An unauthorized person will also be able to retrieve it. Does your recycle bin include credit card information, passwords, medical, or other personal data? Is there sensitive corporate information? Empty the trash or recycle bin on a regular basis to ensure that deleted information stays deleted."
