iPad file permission problem

I have this vlc video player app and I would like to prevent the videos from being deleted through it. I can not turn off the edit function on the vlc app so the only solution I see is to give the videos read only privileges
Unfortunately when I set permissions to 444 (read only) the application is still able to delete the file.  Any advice help

The documents (video in your case) are stored inside of application's sandbox and permissions are not preserved during copy. The only way would be to ask developers to implement such a feature because Parental Controls are not programmatically available.

Thanks for your response
not sure if this applies... i copy the files there myself ... (Phoneview) and then i set the file permission from a terminal app  within the unit  chmod 444 or even an external terminal. ...  I see the file has afterwards 444 but can still be erased. MAybe the sandbox thing still appplies... no idea...

Hi,
I rephrase myself  - permissions are preserved but ignored.

 that's shocking What's the purpose of permissions when they can be ignored.   Thanks for your insight on this.
