When you try to create custom settings for the PDF filter in TMS, no changes are seen in comparison to the Studio created bilingual files.
The PDF filter version in TMS is V22.214.171.124, while in Studio, the version is V126.96.36.199. Because of this difference, the filter settings are ignored by TMS.
The following changes need to be made in the sdlftsettings file:
Change the SettingsGroup ID from "PDF v 188.8.131.52" to "PDF v 184.108.40.206"
Find and replace the following string From: xmlns="http://schemas.datacontract.org/2004/07/Sdl.FileTypeSupport.Filters.MicrosoftOffice.Word.Common" To: xmlns="http://schemas.datacontract.org/2004/07/Sdl.FileTypeSupport.Filters.Word"
Once this is done, TMS will recognize the filter settings file and change the filter. Note: Not all settings will be honored as the newer V3 filter has more options than the V2, but any items not supported will be ignored.
