Some files, even if they are in the sdcard, are not accessible, for instance, try using adb shell to acces a file or directory which owner is not 'sdcard_rw'. If you list a directory content with 'ls -l' you can see that even in sdcard, some files belong to owners like 'app_xxx' which is the UID related to the application that created that file, each application in Android runs in its own Linux process and also has a unique user ID related. I may be wrong since I'm not an experienced android developer, but I know a litle about Linux and Unix, and I can tell you, this OSs won't let unauthorized users to access files or directories which they don't have permission to. To clarify all this topic of Androids security architecture I would recomend reading this section in developer.android.com: http://developer.android.com/guide/topics/security/security.html
