Compiling with front and back matter for a chapter

Re: I can compile bu not what I want it to compile.

I am working on my thesis and I am trying to compile a chapter plus front and back matter
I get the whole thesis compiled sans front and back matter
plus Microsoft does not recognise the file .

just FYI

I will be hoping in my time machine to go back to previously stable version. I hope that the old version can read the newer edits :neutral_face: :confused:
