Thread: Access to drive only with USB stick

Hi,

Id like to setup my computer so access is only allowed to certain drives / folders when a USB stick is plugged in containing a special file.

Im guessing there would need to be two files. One on the computer and one on the stick. When there is a communication access is allowed as normal, when there isnt communication then it denies access.

I dont have a good knowledge of C programming at the moment, but can you please tell me if this is possible first before I begin trying to work it out.
