Every one of us would want to keep our files and folders safe for being censored by others specially our own personal file. Having our filed secured is also the best way to keep your files or folder for accidentally being deleted.
One of the most common ways to secure a file or a folder is to change your folder as “hidden” file or folder. An invisible item is much more difficult to be picked up by those you hide it from. If they do not know where it is, then they do not know where to look in the first place.
Of course, this method is not totally a secure guarantee and chances are someone can manage to set Windows Explorer to show hidden files and folders and from then on it is just a matter of searching for what they are looking for.
Secure Folder http://sourceforge.net/projects/securefolder a freebie tool that offers both folder locking and hiding. The application is free of charge with an easy to use interface. Installation is easy and does not require additional items to the system.
Once you dropped the folder in the application you can choose one of the three security modes for protection: lock (restricts access to the target), hide (makes it invisible in Windows Explorer) and encrypt (encodes the containing information).
A video from 5min.com will walk you through on this application.
