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.<br />

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

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 <br />
Unfortunately when I set permissions to 444 (read only) the application is still able to delete the file. &nbsp;Any advice help

iPad file  permission problem

iOS is a mobile operating system developed by Apple; it is a derivative of the Mac OS X desktop operating system, with which it shares many (but not all) common frameworks and other components. These include Cocoa Touch, the Mach/Darwin/XNU kernel and code from the Berkeley Software Distribution (BSD). Each iOS application runs in its own secure sandbox to prevent altering other applications, the operating system, or any other data.

Programs written for the Apple operating systems are distinguished from software created for other operating systems in that it must be approved by Apple for use on its devices, whether it is from Apple (Final Cut, iWork, Keynote, Logic Pro and GarageBand are popular titles), or is a third party application from Parallels, Nuance, Microsoft and Amazon, among many others.
