The file is opened with CreateFile, then

SetDispositionInformationFile
\Device\HarddiskVolume15\mingw64-x86\sack-r\release_solution\core\src\utils\deploy\CMakeFiles\sack_deploy.dir\DependInfo.cmake.tmp
SUCCESS Delete: True

so when the file is closed it's deleted...

Seems to be set from __archive_mktemp(const char *tmpdir)  passing
FILE_FLAG_DELETE_ON_CLOSE; but my files aren't temporary....
that's the only thing that seems to set that flag....
