Is there any secret file you want to hide? You hope your secret wouldn't be discovered by those who get access to your computer, such as your relatives, friends and colleagues?
This software will meet your needs. It will establish a private and secret space for you where you can save all your documents safely.
The advanced technology will prevent others from finding it and opening it with "search-all" function.

TIPS:
A lot of software is equipped with "recently opened" record. Therefore, please pay attention to clear the records if you want to prevent others from finding out what files you recently opened through these traces. If you couldn't find a way to clear them, you could open many ordinary files elsewhere to overwrite the records.
