Is it safe to point two independent LanguageTool instances to the same path containing ngram files, say, a server instance and a LibreOffice extension? Ngram data installation is described here, but it doesn’t seem to address this question.
I think it should be safe as long as there are no concurrent write operations to the ngram data directory by both instances. So to rephrase the question, is the ngram data directory ever written to by LanguageTool or is it read only?
