Wise Folder Hider is very intuitive and everyone can use it. You only have to select the file that has to be hidden and drag it to the application. Additionally, you can even protect it with a password if you want.
To guarantee a good safety, Wise Folder Hider uses a double password mechanism: the first one, a master key to start the program and, the second one, to hide and unhide the directories individually, the only way to access them.
If you change your mind and want to reveal the information again, you simply have to push the option 'show' on the files and Wise Folder Hider will free them.
In short, it's a good and free tool so that only you can access these files on your computer isolating them from any person who accesses your PC.
It's installed in English by default. Once installed you can change the language.
