<cfset a = "2009 Master Calendar  (4.2.09).xls">

<cfset b = len(listlast(a,'.'))>

<cfset c = left(a,len(a) - b - 1)>

<cfoutput>#c#</cfoutput>

That's a lot more work that it needs to be. One can use listDeleteAt() to drop the last item from the list.

Are the docs somehow unclear?  You did read the docs, right?

What did you try, and in what way did it not work?

But you can see why that's happening, right? That *is* the first element of a dot-separated list, innit? So what you probably need to do is to revise your thinking slightly, and approach it from "how do I get rid of the last element of a list" (the file extension is the last element of a dot-delimited list.

How do you delete stuff from a list?
