Whether on your own computer or a public one, we always have some important or privacy-related files and data that do not want others to see or get. In this case, what we can do is to use some software to protect them in primarily five ways: monitoring (passive), hiding (junior), locking (can be easily hacked by advanced computer users), password protecting (ditto), encrypting (the safest, but not convenient).
Easy File Locker (EFL for short) is a very compact and user-friendly file/folder all-round protection (locking, hiding, etc.). Any file/folder protected by it will not be able to be accessed, no writing, no deleting, or invisible (hidden). Of course, it provides so high degree of freedom that you can set up protective properties as need.
