Which is prefered and recommended way to create custom skins?
I know that i can create skin with Visual Style Builder and compile it with acTelerikStylesAssembly to DLL library, which i can attache to SkinManager etc.
I know that i can copy files from C:\Program Files (x86)\Telerik\UI for ASP.NET AJAX Q1 2015\Skins, rename it with acTelerikStylesRenaming or manual and place them in App_Themes folder etc.
But...
In C:\Program Files (x86)\Telerik\UI for ASP.NET AJAX Q1 2015\Skins subfolders i have more folders and files than in skin *.zip file downloaded from VisualStyleBuilder. Why? If i create two skins by two different ways, my application will be working in the same way and looks great with both skins?
I must create four skins for my application (light and dark for normal users and two high contrast for users with some dysfunction), and this will be hard work for me, that i must know how to make it with minimal effort.
P.S. Sorry for my bad English.
