No built-in file protection mechanisms in Symbian OS 7.0s.

What's enough depends, of course, on how well you want to protect the files and from what kind of users (the average consumer vs. professional user vs. true hackers vs. skilled criminals).

All you can do is to your own encryption/decryption, but if someone really wants to, they can discover the algorithm and keys from your code.

A slightly better level of protection you can get on devices with built-in OMA DRM.

An additional level of protection is provided by Symbian 9 based devices and the Platform Security/datacaging (especially, if you keep the files in phone memory, and not a memory card).

If you combine the last two, you'd be pretty safe for now (at least I haven't heard of anyone breaking OMA DRM v2 or Symbian 9 PlatSec yet).
