No, to you have told not the truth.
For creation of the closed (ciphered) files you should specify it specially. The WOLF-file does not contain in a usual mode DRM and is freely read on all devices supporting this format.
There are two formats WOLF: graphic and тектовый. Graphic WOLF it is perfectly converted from DOC, RTF, PPT, PDF, DjVu and FB2. Formatting, styles and pictures, as in an initial file is thus saved. A lack of this format - the big size of a WOLF-file (usually 15-25 Mb).
If in the book (document) it is possible not to use styles or any elements of a drawing it is possible to use a text WOLF-format. It is better usual TXT. In this format it is possible to write down pictures and it supports a table of contents.
The size of such WOLF-file usually 1,5-2,0 Mb.
For our project lBOOK eReader perfect programs allowing are already created to convert books in a WOLF-format in an automatic and package mode. The received quality of books is much better than similar results at Sony.
