Hello

I do not know if there is built in function to do this, bu tit is extremly easy to write function to do this:

public void create(string file, FileBasedTranslationMemory prevMemory)
        {
            FileBasedTranslationMemory tm = new FileBasedTranslationMemory(file, "", prevMemory.LanguageDirection.SourceLanguage, prevMemory.LanguageDirection.TargetLanguage, prevMemory.FuzzyIndexes, prevMemory.Recognizers);
            tm.FieldDefinitions.AddRange(prevMemory.FieldDefinitions);
            tm.Save();
            
        }

Many thanks, this is as good as having it in the method itself.
