Even in MS_DOS 6.22 days this was not a safe way.
If you want to see, what is inside you just have to use dir and xcopy.
Lets assume you are in parent directory of the alt-char named folder,
TEST is an unused filename, and A is part of this alt-char named folder (verified using dir),
then this is a way to view the files within:
I know of three ways to let nobody watch your files, but sadly i don't know how to batch any of them:
The first is to change the Security settings of the directory.
Right-click the folder, click Properties, and then click the Security tab, and then you can change who should see your folder and files within, ... .
The bad thing is that you may open this directory only with your user login and password.
So if you want to do such on your system you should create a new user only for this, so other don't have access to your main profile.
Another way is, to create a zip file with activated password and add files to these compressed folder, this may be done via VBS or JScript that can be executed on any widows pc via cscript.exe.
The last way is, to install the loopback adapter and create a network share any folder using the loopback adapter. A password can easily set via teh windows dialogs.
None of them is absolutely secure, but if anybody want to break it he or she should be an admin to have a good chance.
Maybe another knows how to batch these things.
