Thanks for the replies! Most appreciated.
I am running Live Mail 2012. I do have the installation file also.
I use G Mail but use windows live to access it on my desktop.
I keep my Documents, My pictures, My Videos, My Music and Favourites on a separate drive.
The only thing on C Drive is the operating system.
I also have installation files for my installed programs.
When I do install Windows 10 which will be after January I will disconnect the other drives before doing so to be on the safe side.
Once again thanks to all for helping.
