Trying to access my files using windows navigator but tools/options etc not helpful

My documents are accessible when I open Libre office but I cannot find them on my hard drives. Can’t find a default folder or designate a folder to store my files.

LO Tools > Options > LibreOffice >Paths shows the path to the Directories that will be used. You can change these. Also if you have a document open and do Save As it will show where the document will be saved.
