I agree that the scripts that auto detect usb storage devices need to be extended to allow the user to have the option to copy the content from the external device to storage managed by the lmce core.
And do some auto cleanup of /mnt/device/XX
IIRC freespire does something similar with the automount, lmce issue is to ask the user if it's a quick camera card they want to copy over or an external 500GB HD they want to leave attached.
Yes I agree Joseph... a very good point. The device management needs to handle the scenario you describe.
