Thanks, Then for application where the user can choose the location of document, you can use it safely only if the store is in a package. If the document is moved/copied, the extern data are also moved/copied.
I had made some test with stores in the Desktop and after your reply I had found many hidden folder for each of my test. And, in the video I talked about, they speak about a new example for Lion that will be available in some weeks. Some weeks have passed since the WWDC and I can't find this example. Is it available only for Xcode 4.2 ?
