It means a string literal, or a string raw, without considering escape characters the \ character acts as escape to insert special characters in string , and because it is a network address, you really want this character to be considered. If you do not use @ , you would have to duplicate the backslash in this way:
string a = "\\servidor01\arquivos"
Here are some other examples of the content that the variable will display.
string a = "hello, world";                // hello, world
string b = @"hello, world";               // hello, world
string c = "hello \t world";              // hello     world
string d = @"hello \t world";             // hello \t world
string e = "Joe said \"Hello\" to me";    // Joe said "Hello" to me
string f = @"Joe said ""Hello"" to me";   // Joe said "Hello" to me
string g = "\\server\share\file.txt"; // \server\share\file.txt
string h = @"\server\share\file.txt";    // \server\share\file.txt

There are number of uses of @ in .Net
1. To avoid multiple sentance formatting error, this means if your string have multi lines then you are bound to use @ symbol to avoid errors otherwise you will need to concatinate string with + symabol after each line.
Console.WriteLine(@"Ram is young,
Ram is honest as well,
beacuse Ram is ram hahaha".

");
2. To avoid escape sequences as mentioned by everyone.

3. In MVC Razor @ is used to bring server side code into client side like
@Html.TextBox();
@Session["username"];

We normally use @ when our string is in complex format which inclue "\\", "\t", or html tags. In such case, @ is used in string in order to display string as it is, ignoring those html, "\n" or "\t" likewise.
