Password locking folders blocks unauthorized access to files, restricts file modification access, prevents data loss and maintains secrecy. Some tools to password lock folders hide encrypted folders from view, preventing unauthorized users from knowing that they exist.
Some operating systems provide built-in options to password protect folders. In other cases, third-party software can be used to password lock folders on local machines or on portable memory units, such as USB drives or external hard drives. Some folder protectors provide a logging system that enables administrators or folder owners to view failed password unlocking attempts.
Using a password locking software that hides the existence of folders protects these folders from being deleted inadvertently or with malicious intent. Some tools also permit the application of permissions on folders. Permissions can restrict what authorized users do with limited data and can also prevent folders from being copied.
For added security, choose password locking tools that come with an encryption algorithm that adds an extra level of security to protected files and folders. Encryption algorithms scramble data indexes, protecting them from hackers who might have gotten through the first level of password protection. Decryption of these folders is possible only with a valid decryption key available to the folder owner or administrator.
