title: How to group files by date using PowerShell?
body: <p>I have a folder with 2000+ files. I want to count the files by date.</p>
  
  <p>so with:</p>
  
  <pre><code>  Mode                LastWriteTime     Length Name  
     ----                -------------     ------ ----  
     -a---        2010-03-15  12:54 AM   10364953 file1.txt  
     -a---        2010-03-15   1:07 AM   10650503 file2.txt  
     -a---        2010-03-16   1:20 AM   10118657 file3.txt  
     -a---        2010-03-16   1:33 AM    9735542 file4.txt  
     -a---        2010-03-18   1:46 AM   10666979 file5.txt  
  </code></pre>
  
  <p>I'd like to see:</p>
  
  <pre><code>Date         Count
  ----------   ------
  2010-03-15   2  
  2010-03-16   2  
  2010-03-18   1
  </code></pre>
  
  <p>Thanks!</p>
