title: C++ Select Folder, Include Files
body: <p>I'm currently working on a qt application for Windows. The user needs to be able to select a directory to load all files from. I am having an issue related to this. It seems pretty stupid, but I keep getting the same feedback. The end users get confused by the file dialog because they navigate to the folder, but it doesn't show any files. Even though they are selecting a folder, it confuses them to not see files in the directory. </p>
  
  <p>So I decided to dig into it and do some research. From what I have uncovered, it seems like there are basically 2 options. The <code>IFileOpenDialog</code> with <code>FOS_PICKFOLDERS</code>, which is what I am currently using via qt's <code>QFileDialog</code>. Or <code>SHBrowseForFolder</code>, which does work, but is pretty limited. </p>
  
  <p>Am I missing any options? It seems like <code>IFileOpenDialog</code> that showed the files without allowing the user to select them would be ideal. Is there any way to accomplish this? I found a lot of older information saying it was not possible, but nothing definitive the is more recent.</p>
