Now we're talking.
1) This thread (and the previous thread) is completely messed up, because you stated you requirements vaguely (drive contents, instead of : one file), with misspelings (driver instead of drive), and the list goes on. When asking questions you should state your final purpose as clearly as possible without pre-conceptions about the technology you want to use or the way you want to go about this. Your final purpose may be unachievable with your preferred technology, or your preferred way, but by putting these in the question, you will only limit people who respond in their creativity. You may get flamed with short abrupt answers (can't be done!), or you may even the attract the ire of short tempered but witty characters, who usually hang around in the Lounge.
2) I'll write a question for you, and you're going to post it in the
General IT Issues[
^] forum of the CP. (quick answers is really for short directed questions, that don't take a lot of answering time.
3) I'm not going to answer your question. My area of expertise is Systems Programming, and although I know kiddie's stuff like C# and Java (I draw the line at Visual Basic), I think they're for whimps who can't even decode the assembler by putting their ear to the processor and listening for opcodes. I only pounce on questions which contain the word 'driver' (like your first question), or IOCTL, or second-level page table translation with predictive caching.
So here's the question you want to ask:
Caption : Protecting a file on a removable drive.
I would like to find out what is the best way of protecting a file on a removable storage media. Users should be not be able to access/decode the contents without going through through a program, also supplied on the removable media. Autorun solutions and solutions which require elevation and/or installation are acceptable. I've googled possible solutions, but this yields conflicting answers. (and a lot of uninformed chaff)
4) Now I'm going to watch the telly. I still have episodes of House MD which I haven't watched, and it takes a bastard to know one.
