Access File List order by ascending help

I frequently use a scanner for records archiving.  I built a quick little DB for the purpose of renaming files, so they are useful to users without needing to give them a database.  As an example, I have copies of forms that are used for medical patients.  I scan the pages for each patient, which makes a PDF.  I then want to rename that file to the patients name, with date or anything else.

Using some code from Dev Ashish's website, I was able to make a nice form that can browse to a directory, list the files, I can pick one, it displays the PDF in a web control object, I can see what the content is and make a new name, which then automatically renames the file.  Works great.

There is one little issue....  The list of files is not alphabetical.  I am looking for someone to give me a code change that would order those files and the directory list if possible.  

Here is the code that I am using for this form:

Option Compare Database
Option Explicit
