Securing Folders

I was looking for a way to make secure CDs and DVDs. I wanted them to be readable in a single PC or accessible in other PCs only if a password was provided. In my searching I came across a utility that seemed to meet my needs; and it had a demo.

In the help file that came with the demo it said, and I paraphrase to keep the program from becoming Googleable (I don't want to appear to be badmouthing the company: )

If you want to secure a CD-RW or DVD-RW take the following steps:

Step A

Step B

Step C


So I did that. Time and time again.

And then I reread the help file and tried some more. And then I Googled for help and found the following:

If you want to secure a CD-RW or DVD-RW take the following steps:

And I tried it some more.

Wait, in all honesty, the first couple of times I did it I was using DVD-Rs. I had to buy $25.00 worth of DVD-RWs to make sure what I was trying was exactly what they were describing.

I could get a DVD-RW to be secure in a single PC, but if I took that DVD-RW to another PC I could see all of the files. This isn't terribly helpful as, if I don't want you to read my DVDs in my PC I just won't let you use my computer.

I read the help file some more and found it online again. I couldn't get The Program to work.

I sent the company an e-mail that explained what I wanted to do. That is, make a CD-RW or DVD-RW readable in only a single PC. The tweaked e-mail follows:

Dear Software Company:

I downloaded and installed your product the other day and have spent a couple hours working with it. I'm having trouble getting it to do what I'd like, and before the demo expires I thought I'd make sure what I want it to do is possible.

I would like to make a DVD-RW with secure folders. And I want the folders to be secure regardless of the PC the DVD-RW is put into.

What I've done:

-- I've used Nero to burn the entire program folder (from c:\program files\folder) to the DVD-RW

-- The Locker was UNLOCKED when I burned the folder to the DVD-RW

-- If I then lock the folder it disappears from the file list on the DVD-RW.

-- Running your program from the PC or DVD-RW and typing in the appropriate password opens the DVD-RW folder, and I'm able to lock it again, and make it disappear.

-- If I put the DVD-RW in another PC, the folder is visible and all the files are accessible from within the folder. All without having to run your program. So, files are not protected on the second PC.

-- I've repeated the above several times. Sometimes when I burn the program directory a DVD-RW I'll have files in the secure folder, other times I won't.

I'm using XP Professional.

(I've got to admit that locking a DVD-RW across multiple PCs sounds like magic and maybe I've misunderstood something. I'd be happy enough to get the DVD-RW to work in just a single PC -- that is, locked so it plays in a single PC.)

You'll notice I mention I think the whole process is magic.

Their reply was similar to this:

Dear Delmer,

Thank you for writing.

If you want to secure a CD-RW or DVD-RW take the following steps:

Step A

Step B

Step C

Sincerely,

The Software Company

"Wait," you are thinking. "That's from the help file." And you're saying this after having read the help file but a single time. I'd read it a dozen or more.

The Software Company sent me a cut & paste piece! It was almost as if they hadn't read my e-mail.

I was a little miffed and cranked out this:

Guys,

I'm guessing that when my original e-mail hit your inbox you had a Don't-these-people-ever-read-the-helpfile-before-asking-a-question moment, which is why you felt the need to cut and paste an answer to me using a paragraph I'd read a dozen times are more. Let me assure you that if I am too stupid to figure something out from a help file, I'm not going to be any better at solving a problem merely by seeing the same text in a different application. Had I thought that were the case I would have simply copied the paragraph in question into Word, then Notepad, then Wordpad, then OpenOffice, etc. until I hit upon the application/paragraph combination that led to Your-Program-Use enlightenment.

You said:

A portion of My Original Mail Said:

-- I've used Nero to burn the entire program folder (from c:\program files\folder) to the DVD-RW

-- The Locker was UNLOCKED when I burned the folder to the DVD-RW

-- I've repeated the above several times. Sometimes when I burn the program directory a DVD-RW I'll have files in the secure folder, other times I won't.


Nero, I assumed you'd know, is a CD/DVD burning program. I guess there is a chance you'd be unfamiliar with it, so perhaps the misunderstanding is my fault. And when I say the Locker was UNLOCKED, I meant OPEN.


What I need to know is:

If I get this all sorted out will I be able to use Your Program to lock a folder on a DVD so that I can take that DVD to another computer and have it appear as if the secure folders are empty.


And then I got called away from my desk. By the time I returned I'd softened a bit and ended up sending this:


Guys,

Thank you for the reply to my question. However, I'd already read the blurb you sent as an answer in Your Program's help file about a dozen times.

I'm an IT guy and spend a large portion of my time answering questions that probably don't need to be asked. The answers often were in an e-mail I'd sent out earlier that nobody bothered to read, or the answer is the same as it was "last week" when the user had had the same, exact problem.

Due to this, I honestly try to find answers before becoming a bother to others. I'd read the help file and I'd gone to the Internet. In both cases multiple times and in each case I fell across the blurb you mailed to me.

There is a very good chance I'm just an idiot and really shouldn't be safeguarding my data from others as it may come about that I will be unable to access the data myself when I need it.

My goal is to somehow protect a DVD-RW so that files on it will only be readable on a single PC (with Your Program installed) or readable on another PC only after a password is entered.

I'm good with a simple "Yes, it can be done," or a "No. Are you insane? That would have to be some kind of wild magic."

If the answer is "Yes, it can be done," I'll keep at it until I sort out how I'm screwing it up or until the demo expires.


If it's "No ..." I'll take a break and head out to the UDF for some ice cream ... Ohio is getting hot.


The Software Company replied. It would seem what I want to do can't be done. The magic needed would be too great. Which was my first thought, but when I read a DVD-RW was needed I thought maybe The Program did some writing/rewriting to the drive.

I know I can encrypt my data using WinZip. It's just that some of the files are large and take a while to decrypt.
