Why should i download my information from Facebook?

Having a copy of your information — whether that is on Facebook or any other service on the web — is an important part of controlling what you share.

In addition, downloading a copy of your information may come in handy if it only exists on Facebook. For example, you may have lost your mobile phone, which contained many photos you took using that phone. If you had uploaded those photos to Facebook, then downloading your information lets you get copies of them back on to your computer.
