Reading files with extension.

I'm using:

A = dir(uigetdir('C:\','Select directory of a files'));

What can I use instead of fullfife() to load only files with file extension *.a ? In this line to have absolute file names?

Thank You.

   A = dir([uigetdir('C:\','Select directory of a files'),'/*.a']);

Thank You it's working but still I don't have absolute file names, fopen returns me -1, is there any solution for this?

A = dir([uigetdir('C:\','Select directory of a files'),'/*.a']);
filename={A.name}

Sorry I have still -1 fid. I wish to use after it this loop:

 for k=1:length(A);

     Ap=A(k).name
     fid = fopen(Ap, 'r');
 end
