Yeah, I went with cfdirectory with the filter and it responded in about 10 ms to my surprise. The folder should stay small, so hopefully it won't slow down too much.

I just tested it with CF5 on a desktop-class machine on a directory of ~ 47,000 GIF and JPEG images each between 15k and 30k in size. CFDIRECTORY with a filename in the "Filter" attribute came back in 120 ms. 20 of that for CFDUMP and 100 for STARTUP, PARSING, & SHUTDOWN. Seems pretty quick to me.
