無料オンラインWPSからRBへのコンバーター

The WPS file format is very similar to the DOC format, it too is a text document but it is created with Microsoft Works Word Processor; and does not include advanced formatting options and macros that a Word document may contain. Most versions of Microsoft Word can open a WPS file, as well as Microsoft Publisher.

Was developed for the first mass-produced e-book reader – Rocket eBook. The format is written in Ruby. RB files are containers holding the entire content for a Rocket eBook device. It has DRM protection capability which is not used in the books published at present due to the format’s lack of popularity.
