Even easier, you just delete the file. When you hard link, there's nothing at all unusual about the files (other than the fact they they are hard-linked to the same disk data). The data itself is, in effect, reference counted, so it won't disappear until the last file using it is deleted. > In modern document-based apps, this would be via the “Duplicate” menu, right? That's one scenario Another scenario is when a new document has been autosaved, which is typically to a local hard disk, and then the user chooses a different volume when prompted to save on closing the window. I may have slightly overstated the case earlier. If your embedded asset file never changes after being created, they you likely won't have any code to clone it yourself, since the NSDocument default behavior does this for you. However, if you don't have an existing file wrapper to trigger this, as when the document is first created, you need to do the cloning yourself. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
