Everyone has one or more files that they want to keep for their own eyes – it could be pictures of loved ones, videos of private nature or some sensitive financial documents. Whatever it is, you can quickly and easily encrypt and hide your sensitive files using the File Commander app in Android. The File Commander app is just like any other file manager or file explorer apps, but it has an extra security feature – ability to encrypt the files and make them invisible.
The File Commander offers a special Secure Mode. In this mode, File Commander all the file operations are performed securely which means that if you save, edit or copy the files they will be automatically encrypted. In order to access this Secure Mode, you can launch the File Commander app and then select Secure Mode from the menu.
The first time you switch to the secure mode, it will ask you for setting up the passphrase that will be used to encrypt the files. Later if you switch to the secure mode, you will have to enter this password before you can proceed. This is why it is vital to use a strong but easy to remember password for this purpose. You can use our PassGen tool to generate passwords for yourself.
Once inside the secure mode, you can save, copy or delete the files. All these file operations would be secure – meaning that all the operations will be encrypted. Furthermore, all the files created or copied inside the secure mode will be visible only from inside the File Commander through the secure mode. They won’t be visible through any other app or when not using the secure mode.
When using the Secure Mode, File Commander shows a red colored ribbon on the top indicating that you are inside the secure mode. While this is very useful feature, but you may not want this when there are nosy people around trying to look at your smartphone over the shoulder.
Fortunately, you can easily disable the secure mode ribbon from the File Commander settings. You can select the Settings from the menu and then uncheck the option labeled Show ribbon in Secure Mode. Now you won’t see the ribbon anymore.
Conclusion: File Commander can be used to encrypt your files in the Android smartphone. The encrypted files are also made invisible outside the File Commander app.
