Upload/Download Controls - Actionscript Questions

I have been using this script for awhile now, and wanted to expand on it some.
I understand most of what is going on here, but-
Can anyone tell me where it sets font size and color for the controls?
I need to make the Font size bigger in the boxes etc…

You can see it work here…

The script is quite long, so it & related .php can be downloaded using the controls…
Or just go to http://downeydesign.com/swfbox/FileReferenceExample/FileReferenceExample.zip to download all the related files.
Thanks
