Or, perhaps, a related product?
Looking for something that will update files when a USB stick is inserted. Needs to synchronize, not just transfer, as there could be multiple, bi-directional changes. Transfer involves only two boxes at present time, but could be expanded to three, perhaps four.
Cannot use stick as primary storage, since data files may be in use when stick transferred. Anything functional is going to be kind of a kludge, I'm afraid.
My hope is something that will run upon insert, then alert me if any of the data files are currently in use on that box.
I'm afraid my explanation is kinda cloudy, sorry.
