macOS Display a message before deleting/renaming a file.

[ithil]

Hi all,

If I try to delete ( by emptying trash) a XCode project, when it is open, it will display a message [The operation cannot be complete because the item "main.m" is in use] & trash is not emptied.

I want to display a similar error message if my application is trying to delete/rename a file, which is used by other application. Is there a way to provide such a behaviour?

Thanks...

Now, someone correct me if I'm wrong, but when you open a stream to a file it registers as being open, now it is possible to test whether there is a stream going into or out of that file based on its location? ID? something? There are many programs that do this, so it is possible - you may want to search for file isopen command or something.

You can't delete a file that is open for writing. That's why the trash gives you that message.

If you want your app to give the same message, open the file for writing.
