Nano,

If we are 100% sure noone uses these any longer, could you please also remove those from the other repos:
https://github.com/QW-Group/mvdsv/tree/master/tools/old_mvs_files
https://github.com/QW-Group/qtv/tree/master/tools/old_mvs_files
https://github.com/QW-Group/mvdparser/tree/master/tools/old_mvs_files
https://github.com/QW-Group/qwfwd/tree/master/tools/old_mvs_files

Thanks!

Visual studio has supported opening cmake project natively for years, and cmake has been able to generate vsproj even longer. It's just noise in the repo and a way to spread out the possible build setup to destroy any sort of overview. Fine to delete. I'll prune the rest as well.

kind reminder: please 'clean' to other repos as well. then we can merge this
