Download TrueCrypt Windows Disk Encryption Tool
TrueCrypt is a free open source Windows disk encryption tool.
I'm using TrueCrypt for keeping my username and password files that I used during filling the registration forms of programming web sites.
I used to use a Microsoft Private Folder tool for keeping my private files and confidential data in a secure folder.
But unfortunately Microsoft does not support Microsoft Private Folder and even Windows Vista as well as Windows 7 does not support installation of this file folder encryption tool.
Microsoft has introduced Windows BitLocker disk encryption tool with Windows Vista.
But users did not use BitLocker with Vista because of its difficulty to use.
Microsoft has enhanced Windows 7 BitLocker and Windows BitLocker to Go for easy use of Windows users to keep their confidential data secure.
But what makes the TrueCrypt preferrable is you can create a file which is a container for other encrypted files.
I downloaded TrueCrypt free Windows disk encryption tool from Download TrueCrypt pages.
It is very small in size and is very easy to install the TrueCrypt.
If you want to use free tool to keep your sensitive files in a confidential folder, I can suggest you to use TrueCrypt disk encryption tool.
