Packing directory output to a list

I am new to this, I have tons of directories that I am working on. I want to output the files in each directory to a comma delimited list with each list named after  the directory containing the files.  So far I have been able to write a code that groups each files underneath each directory but i'm stuck as to the list part, I need help as to packing the output into a list thanks for your assistance.

I have gotten as far as this

<cfset dir = ("D:\dox\")>

<cfdirectory name="Getdir" action="list" directory="#dir#" type="All" recurse="yes">

<cfquery dbtype="query" name="Getfiles">

SELECT * FROM Getdir ORDER BY directory, name </cfquery>

<CFOUTPUT QUERY="GetBoth" GROUP="directory">

<br><B>#GetBoth.directory#</B></FONT><br>

<CFOUTPUT>#GetBoth.name#<BR></CFOUTPUT>

</CFOUTPUT>
