You could try to cd into the directory inst\doc and run the export command to see \
whether it makes any difference.

Can you describe in more details the exact file movement via git add/mv you are doing \
before/after the lyx export command?

Current directory might be different for those two cases?

It tries to detect whether the files is under version control. Not important for \
commandline usage, but if you run with GUI it sets the version control icon bar \
accordingly.

At the moment I don't see anything in the lyx code that would cause deletion of the \
file (or even the directory) itself. Unless it is some sideeffect of running of "git \
ls-files" which I strongly doubt...

We only delete directories in temporary directory (like \
C:/Users/rdboylan/AppData/Local/Temp/3/lyx_tmpdir.PEIeNMGadmvT/) so another option \
coming to my mind is that you are operating inst\doc\msep_num.lyx inside the temp \
dir?
