What that does is first write the file to a temp file, then if all goes well, moves it to the actual location, replacing the original file if it exists. So you'll want to let that happen. But up in saveToURL you should be able to point it to your new dir at a higher level, before writeSafelyToURL does its thing. -- Steve Mills office: 952-818-3871 home: 952-401-6255 cell: 612-803-6157 _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
