title: Get list of files in a specific Netsuite folder
body: <p>I'm trying to retrieve a list of files in a specific folder in the file cabinet.  When I execute the search, I'm given all files in the specified folder and all folders underneath that folder.  I've tried with <code>FileSearchBasic</code> and <code>FileSearchAdvanced</code>, both give me the same results.</p>
  
  <p>Is there a way to get only files in the specified folder id?</p>
  
  <pre><code>var search = new FileSearchBasic
  {
      folder = new SearchMultiSelectField
      {
          @operator = SearchMultiSelectFieldOperator.anyOf,
          @operatorSpecified = true,
          searchValue = new[] { new RecordRef
          {
              internalId = "1234"
          }}
      }
  };
  
  var result = ns.search(search);
  if (result.status.isSuccess)
  {
      foreach (var record in result.recordList)
      {
          if (record is File file)
          {
              Console.WriteLine($"{file.folder.internalId} - {file.name}");
          }
      }
  }
  </code></pre>
  
  <p>This code results in the following list where folder 1236 is a sub folder of folder 1234</p>
  
  <pre><code>1234 - lodash.js
  1234 - dt.timer.js
  1234 - dt.search.js
  1234 - dt.customer.js
  1234 - dt.safeExecute.js
  1236 - processRawLocationData.js
  </code></pre>
