The following review written by one of the Software Informer contributors applies to version 2.0
Secret Disk is a system tool that creates a new, hidden disk in your PC. This small application creates a new virtual drive in your computer that you can show or make invisible with a single click.
This disk can be used to store any kind of sensitive data, giving you the option to protect it with a password.
Secret Disk is a very simple application that uses a wizard to guide you through the drive creation process, which is accompanied by brief and clear instructions. The first thing you're asked to do is create a PIN that will give you access to the program settings and disks. There are two versions of the app; the free version allows the creation of only 1 drive, while in the PRO version you can create up to 20 disks. The PRO version also lets you choose the letter for the new drive. In the free edition, this letter is assigned automatically, the same as the disk size, which is limited to 5GB.
From its simple panel of settings, it is possible to modify the way the Secret Disk works; for example, you can set it to automatically open the disk at Windows start up, choose a new password or remove the existing one, change the interface language, among other options.
In short, Secret Disk offers a simple and hassle-free manner of hiding private files and folders. It works as expected and is extremely easy to use. The only downside is that the free version is very limited.
