The freeware version of Ruby is a very useful application. However, for those users who require additional features, the registered version will provide more benefits. Asides from having all the features of the freeware version, the registered version (Ruby Plus) contains the following features:

1. Language pack support for the user interface (English, Spanish, Polish, Danish, Romanian, and Croatian included with the setup, others can be downloaded). Freeware users can use the language pack functionality on a per-session basis while Ruby Plus users can use it without limitation. Help documentation is currently only in English.
2. Re-scanning a Disc into an existing Ruby ID
3. MP3 information saved as file description (taken from ID3v1 and/or ID3v2)
4. Disc covers - Automated info for covers, load saved covers, and print covers
5. Swap contents of two Discs
6. Browse through the Disc collection via an Explorer-type view
7. Merge multiple databases into a single database
8. Export results to a PDF file

You can visit the payment section to purchase a registration code. There are various payment options such as credit card, check, money order, etc. Once you obtain a registration code you can access the Help>Register menu to input the code into the program.
