Microsoft through its blog post had discussed in-depth about File History earlier today, in case, if you still now know what exactly it is, then well, File History is a backup application that is aims to continuously protects your personal life stored in Libraries, Desktop, Favorites, and Contacts folders. The tech giant made the utility debut during the Windows 8 Consumer Preview time. The feature is introduced in Windows 8 offering new ways to protect files for consumers and supersedes the existing Windows Backup and Restore features of Windows 7. Setting it up is very simple, before you start using File History to back up your files, all you need is to set up a drive to save files to. Using an external drive or network location would be a better option.
