Solution Files

Whilst using Visual Studio 2013, when I created a new web site, the Solution file was placed in:

C:\Users\MyUsername\Documents\Visual Studio 2013\Projects\SiteName\SiteName.sln

and I chose to have the web site files in the following folder:

C:\Web\SiteName\

Last week, I did a clean install of Windows 10 Pro along with Visual Studio 2015.

Now, I can copy over the backups of:

C:\Web\SiteNameA\
C:\Web\SiteNameB\
C:\Web\SiteNameC\

But, how do I have NEW web site solution files for each site?

C:\Users\MyUsername\Documents\Visual Studio 2015\Projects\SiteNameA\SiteNameA.sln
C:\Users\MyUsername\Documents\Visual Studio 2015\Projects\SiteNameB\SiteNameB.sln
C:\Users\MyUsername\Documents\Visual Studio 2015\Projects\SiteNameC\SiteNameC.sln

I have approximately 75 different solutions (.sln) and I don't want to manually recreate them if there is an easier way ...
