Wix Toolset: How to create multiple folders? - wix

Question

I'm a beginner in WIX. I want to create multiple folders inside the main folder, but ending with just one folder. Can someone help me on how to create multiple folders?
<!-- Step 1: Define the directory structure -->
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="ProgramFilesFolder">
<Directory Id="APPLICATIONROOTDIRECTORY" Name="TEST">
<Directory Id="HTML" Name="HTML" />
</Directory>
</Directory>
</Directory>
<!-- Step 2: Add files to your installer package -->
<DirectoryRef Id="APPLICATIONROOTDIRECTORY">
<Component Id="NewSHU_TM.exe" Guid="3977B09E-B696-471A-9C29-419301EDF6A0">
<File Id="NewSHU_TM.exe" Source="C:\Program Files\Debug\NewSHU_TM.exe" KeyPath="yes" Checksum="yes"/>
</Component>
</DirectoryRef>
<DirectoryRef Id="HTML">
<Component Id="exec.html" Guid="61D58D90-F9A3-4649-9113-6AD7B1249DE8">
<File Id="exec.html" Source="C:\Program Files\Debug\HTML\exec.html" KeyPath="yes" Checksum="yes"/>
<File Id="exec_001.html" Source="C:\Program Files\Debug\HTML\exec_001.html" KeyPath="no" Checksum="yes"/>
</Component>
</DirectoryRef>
<!-- Step 3: Tell WiX to install the files -->
<Feature Id="MainApplication" Title="Main Application" Level="1">
<ComponentRef Id="NewSHU_TM.exe" />
<ComponentRef Id="exec.html"/>
<!--<ComponentRef Id="documentation.html" />-->
</Feature>
</Product>

Answer 1

You need to nest the directories you want to install to within TARGETDIR:
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="ProgramFilesFolder">
<Directory Id="INSTALLDIR" Name="Example">
<Component Id="ApplicationFiles" Guid="12345678-1234-1234-1234-222222222222">
<File Id="ApplicationFile1" Source="example.exe"/>
</Component>
</Directory>
</Directory>
</Directory>

Answer 2

You need to close each "Directory" element. Please notice the endding "/>" in the "TEST" and "HTML" folder below.
The following will create (given you are adding files to these directories) the two folders at the same level under the "Example" folder:
c:\Program Files (x86)\Example\TEST and
c:\Program Files (x86)\Example\HTML
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="ProgramFilesFolder">
<Directory Id="INSTALLDIR" Name="Example">
<Directory Id="ChildFolder1" Name="TEST" />
<Directory Id="ChildFolder2" Name="HTML" />
</Directory>
</Directory>
