I set up two external usb drives with folder hider. Both are off a lot of the time or disconnected. At some point, one or both of the devices no longer showed in the folder hider list.
I generally close it down by clicking the X in folder hider's workspace and the drives return to hidden. The problem seemed to be caused when working with one drive (and not the other) and shutting down.
I am not sure why the program would not recognize the drive(s) it is registered to. Is something written to the external drives linking it back to the program?
So I set them up with a secondary password.
I am trying to insure that the drives stay linked and that their content stays hidden when disconnected, so I created secondary passwords hoping that
this will be helpful.
