The Windows version of Ovation Pro uses exactly the same file format as the RISC OS version - that means you can load documents produced on RISC OS into a copy of Ovation Pro running on Windows. No changes are needed to do this, for example Sprites and Draw graphics will appear.
On Windows Ovation Pro files should be given the extension .dpd.
The only exceptions are ArtWorks files which it is unlikely will ever be visible on Windows, and .bmp files which the RISC OS version does not support at the moment.
Ovation Pro was supplied on CD. The complete CD contents are accessible from web pages, just click on the link below.
The CD contains documentation, bundled software, filters etc.
