How to run a job that will check if files exist?

I have a folder 'realtime' that has about 15 txt files(test1.txt,other.txt etc), theres is other jobs nothing related to coldfusion that if something goes down then the file wont exist anymore.

So I want to create a job that if a txt file doesnt exist then it will sent me a email.

what would be the best way to do something like this?

would i have to check for each individual txt file , something like ??

<cfset Pathtest = "\\folder1\dept\Alerts\other.txt"><cfif !fileExists(Pathtest)>  <cfmail ...>  sent me a email  </cfmail>   </cfif>
