There are a sheer number of folder encryption
utilities available out there that allow users to encrypt folders and
files via staunch encryption algorithms. Although such encryption tools
provide a powerful way to protect confidential data, most users find it
tedious to decrypt the encrypted folders and files every time they want
to use their data. If you’re looking for a simple yet a powerful tool
that can password-protect your important folders, then
Folder Lock
is a solid pick. It’s a beautiful application for Windows that lets you
quickly and conveniently add password protection to your confidential
data via drag and drop. I
t can hide the folders in such a way that it is not possible to disable their hidden attribute, or locate them via Windows Search.
For
first time usage, it asks you to enter the password that you want to
use to protect the application as well as folders from external,
unauthorized access.
To begin, launch the application, create a new password and start
dragging the folders that you want to protect over the application’s
interface.

The main interface has Select All and Deselect All buttons at the
top, while Add Items, Lock Selected, Unlock Selected, Remove Selected
and Remove All Items can be accessed from the bottom of the window. It
shows you all the locked files, along with their names and source path.
Unlocking folders/files is easy, just select the files/folders you want
to unlock and then select Unlock Selected.

The Settings button allows you to specify default behavior of the
application including automatically unlock all items upon login and
automatically lock all items upon logoff. You can also change the master
password using the Change Password button.

Folder Lock works on both 32-bit and 64-bit versions of Windows XP, Windows Vista, Windows 7 and Windows 8.
