(1) MetaTexis can import and export TRADOS documents. (If there are no footnotes, there are no problems. If there are footnotes, one needs to be watchful. The problem is that TRADOS deals with footnotes in a strange way.)
(2) MetaTexis NET/Office can directly use the TRADOS Workbench as a database engine. MetaTexis Pro and Lite cannot use TRADOS databases directly. However, MetaTexis can import TRADOS and TMX databases, and it can export TMX databases which can be imported by TRADOS.
