Creating a directory before using cffile

Question

I'm having trouble using cffile right before I create a directory. I am using the cffileupload tag and my url attribute is a page that has the following code. Basically the code below creates a new directory and uploads all the images to that directory. However, it fails on the 2nd upload and i get a 500 error in the cffileupload flash object. However, if I hardcode the directory path, they all upload fine. Anyone know why I am having this problem?
<!--- User will upload all the images to a temp directory based on date and time --->
<cfset uploadFolderPath = "C:\ColdFusion9\wwwroot\MyApplication\uploads\" />
<cfset date=DateFormat(Now(),'mm-dd-yyyy_') />
<cfset time=TimeFormat(Now(),'hh-mm-ss') />
<cfset newFolderName = "upload_" & date & time />
<cfset newFolder = uploadFolderPath & newFolderName />
<cfdirectory action = "create" directory="#newFolder#" />
<cffile action="uploadall" destination="#newFolder#" nameconflict="makeunique" />

Answer 1

It seems unlikely to be your problem, but be aware that <cffileupload> calls that URL once for each file uploaded, not just once.  That means the <cfdirectory> could conceivably be called twice within the same second, meaning the second call to it might fail because the dir already exists.
You should probably check the dir exists before just assuming you're OK to create it.
