I'd say setup a scheduled task to run as often as you need it to, that deletes these files.  How do you store the .tmp files?  All in one folder, or a new folder each time?  What you want to watch out for is deleting any .tmp files that are still required.  You could use the date last modified attribute (if doing a cfdirectory) if they're all in the same folder.

Under what circumstances are these tmp files created?
During file upload?
Could you explain a bit more - for ex. was the creation of these tmp files written on purpose by someone?
Are they under the website directory or are they in the windows ColdFusion temp directory?

(no points please)

Some processes in CF may create temporary files. For example file uploading, charting, etc... But CF typically those files itself, automatically  So as mentioned, please clarify whether you are talking about those types of files ... or some other temporary files _you_ create explicitly within your application code.

without asking why are you doing this ...

<CFDIRECTORY action="list" listinfo="name" type="file" directory="#Application.tempDir#" filter="*.tmp" name="files">
<cfloop query="files">
      <cfif fileExists(Application.tempDir & files.name)>
            <cfset fileDelete(Application.tempDir & files.name)>
      </cfif>
</cfloop>

Just wondering ... but is there a reason you need to do this? In many cases it's not necessary to have physical files since a lot of cf tags work with blobs as well.
