title: Batch file script concatenate strings
body: <p>I want to concatenate strings in a batch file because I need to parameterize in the batch file (.bat) to use paths frequently. So instead of writing:</p>
  
  <pre><code>ren "C:\Folder\Sub Folder\filename.ext.tmp" "C:\Folder\Sub Folder\filename.ext"
  del "C:\Folder\Sub Folder\filename.ext.tmp"
  </code></pre>
  
  <p>I would like to write something like</p>
  
  <pre><code>set pathString="C:\Folder\Sub Folder\"
  ren pathString+"filename.ext.tmp" pathString+"filename.ext"
  del pathString+"filename.ext.tmp"
  </code></pre>
  
  <p>Is this somehow doable? If so how? Thanks!</p>
