Microsoft releases a new ‘contacts+message backup’ app for Windows Phone 8.1 users
Microsoft has released an app that enables you to make backup of all your contacts and messages and store it in your phone’s SD card. Appropriately dubbed contacts+message backup, the app is compatible with Windows Phone 8.1 devices.
After installation, you can access the app by heading to Settings on your phone – it doesn’t appear in your regular list of installed apps. The backup it creates is stored in a folder named backup+restore.
Another couple of important points worth noting are: the app backs up contacts in VCF format and messages (SMS & MMS including attachments) in XML format, and for dual-SIM phones, it works only for the first SIM. You can download the app from the Windows Phone Store for free.
