ES File Explorer shows empty /data/ folder I'm looking for the whatsapp key file on my phone (which should be stored in /data/data/com.whatsapp/files/key).

Therefore I:


Rooted the phone Galaxy S5 (Android 4.4.2)
Checked the root status with Root Checker (it's rooted!)
Downloaded ES File Explorer
Opened /data/ folder in order to find the key file with ES File Explorer...


but the folder is empty!

Is that folder really empty or am I missing something?
You have to configure ES to use root.

Menu &rarr; Tools &rarr; turn Root Explorer to "ON".
