How to query for specific filename

Question

I'm using a modified folder_action script to ftp files up to a server once they're finished being created.
Is there a way to query for a specific filename to be present in the folder prior to passing it to the actual ftp function? The catch is that the filename will always be in the format of <mmddyy>.mp4. During the process that is creating the actual file to be ftp'd, various temp files are created prior. I'd like to ensure that only the final version of the mp4 is acted upon, which is the one with the mmddyy as the filename.

The folder action already has the folder and the item paths passed to it, so you can get the individual file name by using something like:
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #FFDDFF;
overflow: auto;"
title="this text can be pasted into the Script Editor">
on adding folder items to this_folder after receiving added_items
repeat with AnItem in added_items
if text (count (this_folder as text)) thru -1 of (AnItem as text) is "<mmddyy>.mp4" then
-- whatever
end if
end repeat
end adding folder items to
</pre>
There are also temporary folders that the system provides, so you shouldn't have to use the folder with the attached action at all:
get path to temporary items
get path to temporary items from user domain
