Supported formats
This table is generated from the same data the product itself uses. The app cannot claim more than what is listed here.
What "under validation" means
A format that looks technically feasible but has not yet been proven against real files. Until it is, we do not list it as supported. HWP is currently in this state.
The Viewing and Editing columns show the best level reached on any supported platform. It can be lower on a given platform.
