I think QFile::permissions might be what you are looking for.  This is  
very platform dependent stuff and it depends what your OS is and user  
level of who might be trying to trash your file.  Many systems will  
lock a file if it is opened by an application so the problem you are  
anticipating might not be a problem at all.
