Definitely needs support for Windows Phone

Needs to be able to support Windows to Android (and reverse), Windows to iPhone (and reverse), and Windows to Windows. I have a Windows phone, and at present this program is of absolutely no value to me until Windows Phone is supported. Also, backup of any phone -- essential prior to any major upgrade of the phone, like upgrading Windows Phone's current version to the new Windows Phone 10 system due out soon, is essential.
