Actually, even with a java.io.FileFilter, the java method is quite a bit slower than cfdirectory, if doing recursion and sizes, etc.. Somehow I'm thinking that cfdirectory is some java that uses "native" FS stuff vs. java FS stuff, but I'm no java guru, and don't really know. Your blog entry got me thinking, ages ago. Never posted the results, did I? Sheesh, I'm weeeeeeaaaak! I don't even know where I put that... Guess the answer is, for recursion, something native, or cfdir; otherwise, java is WAY faster (for just a list file names for a given dir). :den ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:250089 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
