In case you get the feeling how convenient Sharky can be in your everydays document shuffling, you will probably want to register it and get the advantage of compresing, encrypting and history-tracking of your files. The procedure is simple - as soon as you buy the license and get your serial number, you can go to Preferences and then Registration tab. Enter your e-mail or Name you used to purchase the license, then fill in your serial number and personal control code. That is all you have to do.

You can continue using Sharky even without purchase and registration, but the number of files you can archive will be limited to 100 and advanced features mentioned above will not be available. Well, that's the way of the World... no (completely) free lunch!

Of course, even if you do not purchase, we will still be glad to hear your comments, suggestions and (even!) critics. :-)
