We have deprecated the XML/XHTML v1 File filters used by Trados Enterprise. This means that creation of v1 based filters is disabled.
We recommend all users and customers to use the XML v2 File filter which supports all v1 functionality, provides higher performance and has bugs resolved.
Existing v1 configurations can still be used and modified. Existing projects will also not be affected.
Instructions on how to migrate from v1 to v2 can be found here: https://docs.rws.com/791595/981251/trados-enterprise/migrating-xml-v1-based-file-type-configurations-in-------------trados-studio
