Basic Directory addition help

Hey all,
I am new to creating the installer, not to scripting.
However I can't seem to figure out how to add a sub directory to my nstall script with additional reference files in the subdirectory.
Under my install section I can ad flies with:
file "myfile.ext"
But what's the command for adding a directory?
I tried:
Dir
dir
directory
Directory

Nothing seems to be working.
Thanks for any ideas.

File /r "c:\something\*"

If you can't take the time to read the manual you are going to run in to a lot of issues like this, it is better to just take 10 minutes and quickly scan through it...
