Jeff,
I've read there are issues with file/directory operations in CF when files
are really large or the directory contains TONS of files. You might try a
java alternative. I'm mobile right now, but I think it's something like
this:
createObject("java", "java.io.File").init( filePath & fileName ).exists();
