Move photo files based on photo names in text file

I have a list of photos that contains the names of photos that I would like to separate from a large directory of photo files. Since this would be a time consuming project to perform by hand I would like to automate the process with Coldfusion. What I want to do is put together a Coldfusion script that when run will look at the photo names in a text file and then check to see if they are present in the master photo directory. If a photo listed in the list is found in the photo directory Coldfusion would then copy each photo it finds to a new directory. Does anyone have code that could perform this task?

Here is a sampling of photo names in the text files and the photo names match exactly the photo names in the master photo directory.

Did you accidentally omit the sampling in the original post?

Caveat - This example as some debugging code in it.  

1) It prints a message if the file doesn't exist
2) If the file already exists in the destination directory, it does _not_ overwrite it.  You can change that if you prefer
<!--- read list of photos --->
<cffile action="read" file="c:\yourDirectory\listOfPhotos.txt" variable="fileContent">
<!--- directories must end with "\" --->
<cfset sourceDirectory = "c:\yourDirectory\">
<cfset destinationDirectory = "c:\otherDirectory\">
<cfloop list="#fileContent#" index="fileName" delimiters="#chr(13)##chr(10)#">
	<cfif FileExists("#sourceDirectory##fileName#")>
		<cfif NOT FileExists("#destinationDirectory##fileName#")>
			<cffile action="copy" 
				source="#sourceDirectory##fileName#" 
				destination="#destinationDirectory##fileName#">
		<cfelse>
			<cfoutput>
			Error. File #fileName# already exists om #destinationDirectory#<br>
			</cfoutput>
		</cfif>
	<cfelse>
		<cfoutput>Skipped. File not found ... #sourceDirectory##fileName#<br></cfoutput>
	</cfif>
</cfloop>

Another home run! Worked perfectly and I really like the reporting feature you added, that was a big plus!
Again this one worked perfectly the very first time. I was amazed how fast I was able to process over 1400 files even on our slow local network. Thanks so much!

Very useful code for verifying and separating files. It is so well written that I believe it could be easily modified to perform other file tasks.

Yes, for moderate size files it does pretty well :)

Btw, I'm sure you noticed it does a "copy" of the files, not a "move".  I think is what you wanted.  If you wanted to "move" the files instead, change the code to

<cffile action="move" ...>
