I have a USB device that by itself writes to some built-in flash memory.  When it's plugged into a PC, it works like a USB mass storage device with a FAT fs.The device cannot be configured in any way other than to configure its filesystem from a PC.I would like to simply hide the files that this device writes to its filesystem.Is there a way to configure a FAT fs so that it accepts writes like normal but the directory structure cannot be viewed on a PC without me using a special command like changing permissions or setting a flag?The hiddenness doesn't need to protect from technically skilled people of any sort, just compulsive prying eyes. So something as simple as requiring the viewer to type a flag on ls would be good enough. But the hiding mechanism must work on Windows, Mac, and *nix.
