Using the Secured files interface, available in File Commander Premium, allows you to keep your most important documents and files safe and secure. Any file or folder that is placed in the Secured files category will be encrypted and invisible outside of File Commander. The secure mode will also prompt for a passphrase in order to access it. Be mindful of the passphrase you select, once set it will be stored on your device and will not be recoverable.
Selecting a folder will open it in the Internal storage interface alongside all of its file and folder manipulation options.
