I want to see the files from
/root/data/data folder. Is there any application/trick which can do this?
You cannot do that without having your device rooted, as the file permissions won't allow you to list contents there. You will be able to change into
While one might be able to access
This is what happens on a device without root (output created just now on my Cat Stargate 2 running Android 4.1.1). Repeating the same on my HTC Wildfire running CM9 (Android 4.0.4) and having root access enabled looks a little different, and should give us the wanted details (output cut to the necessary stuff):
As it is clearly shown,
Simply use a file manager app like AndroZip File Manager
Keep in mind that you cannot edit the files if you do not have root access. It is not harmful only to read the files though.
You can do it with ES File Explorer(Only if your device is rooted)
Step 4: Access any system folder
