Security issues is one of the most important aspects in the world of information technology. Now this to group the data inserted into a specific folder for easier searching later. When we work with the data or the computer connected to the public network, it is important to protect our data file from the access of people who we do not want.

One method for protecting data files and restrict access to it is a combination lock folder with a cryptographic algorithm. Shift cipher is an algorithm that existed before the digital era as it is today. Classical algorithm included in the cryptographic system symmetry is an algorithm that have the same key to encrypt and decrypt. That's because at that time undiscovered public key cryptography.

Based on the results of testing an application or system built lock folders with shift cipher algorithm that is built with java and have been made in the extension jar has been tested with a lock on the folder, it works by adding a registry extension network. Folders are not in lock-in the form of a regular folder icon while a folder that was in-form lock icon Network icon in a state of hidden and when clicked it will go to Network. The result can be run properly to protect access to the folder with the terms of the computer is installed java minimum version of Java 2 SE 1.2.
