That's quite odd; I don't believe there is any specific code to do
that, nor can I think of a reason why it would. Two questions:

1) Can you run "/usr/libexec/qmi-proxy --version" and let us know the
version?

2) Can you run "sudo strace ~/qmi-proxy" after copying to your home
directory, and attach the resulting output to a reply? The strace
should capture any file deletion done by qmi-proxy itself, if it is
indeed qmi-proxy doing the delete.

Thanks,
Dan
