Asus WebStorage suddenly stopped asking for a login/password. I mistakenly clicked on the icon below Computer and it just asked for EULA agreement. Then I've been able to use the dedicated 1000 GB storage for my backups. Asus support told me a couple of months ago that U30JC-QX010X had no WebStorage offer included.
This is just a 2 months trial.
Asus WebStorage pollutes all synchronized folders with .awo directories.
You cannot disable default folders (Favorites, Documents and some BackupDemo folder on the desktop).
