Prevent access of documents directory in organizer of iphone application

From organiz开发者_运维知识库er window i can copy document directory data. But in some apps i noticed that

it is locked and cant access documents directory.How can i lock the application from accessing

documents directory via organizer.

I suppose you can access documents directory of applications that are signed with provisioning profile installed on your computer. Imo it is a handy feature for developer purposes. However it is disabled for applications downloaded from appstore so why should you worry about it?
