Below is the source code. Hope experts can write v3.0, hehe!! :P
But when using it, it should be used in exe format. Otherwise, if the source code is seen, the security will be reduced oh (but if there is no password, no one can see the confidential file),!:P
The download of the exe format file of Windows File Confidential Expert can be found at: http://tianzizhi.disk365.cn/

Hehe, I think this one is better.
http://www.cn-dos.net/forum/viewthread.php?tid=23441&fpage=1&highlight=%E5%8A%A0%E5%AF%86

If you want to use it on other machines, you can use WinRAR to archive. There is an option in WinRAR whether to add stream data.

Well, it is suggested not to say "encryption", just say "camouflage" instead

I use "confidential" because it sounds better, using "camouflage" doesn't sound good, heh heh....

Great stuff! Learning!

Good stuff, do try it.
