I am extremely excited for the new updates to the filesystem mechanic and I am super hyped for the data vaults, the only thing I really wish for now is the ability to copy data instead of purely moving it. Right now there is seemingly no way to take data from one memory device or another without also removing said data from the original device.
For data vaults, this would mean that getting stealing data would be very roundabout in needing to read and manually copy files down into a new file. And adding new data to the data vault would require losing your own copy.
