title: Wolfram Mathematica import data from multiple files
body: <p>I have a lot of files. Every of which contains data.
  I can happy import one file to Mathematica. But there are more than 500 hundreds of files.
  I do it so:</p>
  
  <pre><code> Import["~/math/third_ks/mixed_matrices/1.dat", "Table"];
   aaaa = %
    (*OUTPUT  - some data, I can access them!*)
  </code></pre>
  
  <p>All that I want is just to make circle(I can do it), but I cannot change name of file - 1.dat.  I want to change it.</p>
  
  <p>I tried to make such solution. I generated part of possible names and I have written them to separated file.</p>
  
  <pre><code>Import["~/math/third_ks/mixed_matrices/generate_name_of_files.dat", "Table"];
  aaaa = %
  </code></pre>
  
  <p>Output:  <code>{{"~/math/third_ks/mixed_matrices/0.dat"}, \</code><br>
              <code>{"~/math/third_ks/mixed_matrices/1.dat"}, ......</code></p>
  
  <p>All that I want to do is <code>Table[a=Import[aaaa[[i]] ,{i,1,500}]</code></p>
  
  <p>But the function <code>Import</code> accepts only  <code>String</code> " " objects as filename/paths.</p>
