Another thread mentions the use of DataLocker to protect data with, inter alia, DropBox. I've had DataLocker for a while now, but it comes without any help file, manual or instructions so I have no real idea how to use it. I run DropBox across three Macs, two under MacOSX.4.11 and one under MacOSX.6.8, as well as onto my iPad but I have no idea how to implement the added security of DataLocker. I did read, whilst Googling a few days since, that it only works on files uploaded to DropBox since DataLocker was installed but I can't find that review now so aren't sure if I dreamt it! Can anyone help with some simple (for a very simple questioner) instructions on how to install and implement this seemingly useful app? Do i need it on all four devices? Does it need configuring on any or all of those devices - and if so, how on earth do I do it? How do I "link it" to my DropBox account as stated on this Techcrunch page? What appears to be a highly regarded piece of software is let down by the seeming lack of any documentation - although, as I said above, I am a very simple questioner! Many thanks in advance.
