I want to open some file from my application, file are created by the application itself and can have read or write permission.

I set read permission file with: 

chmod 400 path

I want read permission file don’t show unlock dialog when the user try to edit such files.

Is there any FS flags that can help me?

Here 2 images about the involved dialogs
