GCstar is an open source collections manager software. Collection managers are databases optimized for collecting information on similar things. For example, I have a bunch of DVD movies that I have ripped to my computer for easy viewing. Unfortunately, they have been saved in different locations.
Using GCstar, I can create a movie collection database and import the full file paths of all the movies I have on my computer. This way, I am able to access my movies from one single interface.

cron and it will execute the task at the given time and date.
Bcrypt is a cross platform file encryption tool that uses the Blowfish encryption algorithm. One of the chief advantages of using bcrypt (apart from the security aspect) is that it runs on a wide variety of OS platforms and hardware architectures. This includes Windows, Linux, Mac OS X, BSD, HP-UX etc. This means, you can encrypt the file in say Linux, and then move the encrypted file to a machine running Windows and decrypt the file over there.
