Facebook recently introduced a new option to download all your information of your Facebook account. You can download all Facebook album/ photos together in a single click. Also you can download your all Facebook statuses, Wall posts, friend list, Messages, Notes etc.
The option enables to take backup of your Facebook account. But there is no way to upload the downloaded data back if your account gets deleted or when you create a new profile.
The downloaded file contains following things managed very nicely in HTML (browser viewable) format.
To download Facebook account backup visit:
Click ‘Download your information’ and Press download button. Facebook will generate whole backup of your account and will send you a mail notification.
When you will try to download generated zip file you will be asked to verify your identity by entering your account password and/or other verification methods. (After download you need to extract zip file and open index.html file)
So whenever you want to browse your Facebook profile offline where internet is not available just have a backup with you.
