What are the files of folder wwwroot /Content/2012.1.214 used for?

They look like themes of some sort?

They are the telerik theme files.  Telerik is used for the grids, etc. in the admin.  Nopcommerce uses the Vista theme.  If you change the theme it changes the look of the grids,some of the buttons, and menu in the admin.

I changed mine to Office2010Silver and added my own logo and header on the administration side and I really like how it looks!  

Try out some of the themes and see how you like them.

Here's how:

In Visual Studio go to

Nop.Admin  -> Views -> Shared -> _AdminLayout.cshtml


In _AdminLayout.cshtml

Scroll down to

---------------------------------------------------------------

@(Html.Telerik().StyleSheetRegistrar()
        .DefaultGroup(group => group
            .Add("telerik.common.min.css")
            .Add("telerik.vista.min.css")
            .Add("telerik.rtl.min.css")
            //uncomment the lines below in order to combine and compress CSS files
            //.Combined(true)
            //.Compress(true)
            ))

---------------------------------------------------------------

Change the "telerik.vista.min.css" to the CSS file of the theme you want to try in the 2012.1.214 folder.  

For example: "telerik.office2010silver.min.css"

Next save your changes and push F5.

Hope this helps.

Aha!
That's excellent mate.

Just tried WebBlue - it's fairly cool.

I hadn't considered themes or styling in the admin area!

Telerik bought up Fiddler today!

I know what you mean.  I didn't change the theme on the admin area at first but I found that as a store owner you spend so much time on the administration side that it is nice to get the look and feel to match your business.

The nice thing about the Telerik themes is that by changing the theme you can make big changes.

Where can I find the list of themes bundled into the Nop Telerik dlls?  The new stuff on Telerik's website seems to be different.
