How do you copy a set of files to multiple places using Wix?

Question

I'm trying to make an install that puts a copy of the same files in multiple places...

is there a simple way to do this?

eg. if I wanted to put a.txt b.txt c.txt into all of the following directories :-

.\Blah\
.\Txts\
.\Examples\

Simply create multiple components which reference the same file, but install it to different locations. The only gotcha is that you cannot use two <File Source="somefile"/> elements referencing the same file because they will get the same auto-generated ID. Explicitly give the file elements different IDs to avoid that problem.

<DirectoryRef Id="directory1">
   <Component Id="somefile-component1">
      <File Id="somefile-id1" Source="/path/to/somefile"/>
   </Component>
</DirectoryRef>

<DirectoryRef Id="directory2">
   <Component Id="somefile-component2">
      <File Id="somefile-id2" Source="/path/to/somefile"/>
   </Component>
</DirectoryRef>
