I will be travelling for a training & in a weeks time I will be giving presentation which will be on usb drive & dvds. My past experience is that people have a habbit of asking shamelessly, or connecting & copying the data from usb drive. I will be using 3rd party laptop / desktop. So I want some software which ask for a password when opening a file or a folder, it should not require same software on 3rd party computer. Is it possible, if yes any software to do this, any user experience to be shared. Searching the forum I see lot many threads to copy protect CDs but what I want is password protect folders on cd, so even if they copy they cannot open the folder.
