In ubuntu Libreoffice cannot open files from windows directory

In ubuntu:
when trying to open a libreoffice-file from a windows directory it does not work. Files from ubuntu doc directory can be opened without a problem.

I understand the need to close duplicate questions. I am not sure how to get to the question/answer that was duplicated. Wouldn’t it be a good idea to include a clear link to the original question/answer when closing a duplicate? Perhaps that is already being done, but I find only a link to the duplicate question’s writer, which can lead me back to the duplicate question but no closer to any answer.
