>From the content of your predicate, it looks like you're running a Spotlight query (NSMetadataQuery), as such, the spotlight-dev list might be a better place for this. The Spotlight query syntax the the NSPredicate syntax aren't quite the same, and the behind-the-scenes conversion leaves a bit to be desired. I remember running into a situation similar to what you're trying a while ago, and eventually giving up and construcing my own Spotlight query strings and using MDQuery to run them. <http://developer.apple.com/documentation/Cocoa/Conceptual/Predicates/Articles/pSpotlightComparison.html> Do you get the error if you change your predicates to: kMDItemFSName != %@ Some else to keep in mind is that there is (or, was the last time I checked---10.4) an upper-limit to the length of Spotlight queries. If this list of files is going to get BIG, then you may want to re-consider your approach, or do the filtering after you have the results.
