[wix-users] Set Directory in WiX

I am trying to create a folder at a location different from the application
installation location which happens to be C:\Program Files(x86). I am using
the following fragment

    <DirectoryRef Id="TARGETDIR">
      <Directory Id="PhotosDir" Name="Photos" />
    <!--<SetDirectory Id="PhotosDir" Value="[TARGETDIR]Photos"

  I tried with a SetDirectory element as shown above and also with a
CustomAction as shown below. (If I use both, I get an error saying Id is
duplicated. Hence I commented it.)

  <CustomAction Id="SetPhotosDir" Directory="PhotosDir"
      <Custom Action="SetPhotosDir" Before="CreateFolders"/>
  I have a component also defined for this directory element as below.

  <Component Id="cmpPhotosDir"
Guid="{8F757344-CA0A-42BC-B292-A51CE86B19E2}" KeyPath="yes"

  But the directory called Photos is always getting created in D drive,
even though it is nested inside of TARGETDIR. I actually want to control
the location where this directory gets created, probably through UI. I
googled for SetDirectory element example, but couldn't find a proper
working sample. All I get to see is that I have to use a custom action type
35 or 51. But it is not clear what code should go inside of these custom
actions. Also, I am not sure, if these custom actions are required in
addition to the SetDirectory element or not. Can anyone please help me
achieve this, with some working sample?
