At least I think that this is the problem. I have changed from Windows 10 to linux mint and I have a lot of data folders, files and documents in my original windows NTFS formatted data locations. In the linux file manager I can see the folders and files, I can open them and there is an option for me to choose whether I want to edit them, I say yes, do the editing but then when I go to save the document via Libreoffice I cannot save it. Same if I make a new document in Libreoffice. I cannot save into my old windows data area.
