That's a good point, Mike. In my app, I want to provide file operation but try to restrict them if they're going to fail. I still handle the failures in my code but I feel it's a better user experience that they know in advance, for example, that a file is locked and thus I won't be able to delete it or replace it. -Laurent. -- Laurent Daudelin AIM/iChat/Skype:LaurentDaudelin http://www.nemesys-soft.com/ Logiciels Nemesys Software laur...@nemesys-soft.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
