Reading files in a specified order

I have multiple files of the same type in a directory that all have the same beginning, say "A11_K", followed by a numbers specific to the file. For example

A11_K25-1.txt

A11_K25-2.txt

A11_K27-1.txt

I know I can read all of the files of that type using something like files = dir('A11_K*') but how do I make sure I read them, in the numeric order following the K above as in the example list?

Download NATSORTFILES here:

and use it like this:

S = dir('A11_K*.txt'); 
S = natsortfiles(S);
