I was able to reproduce the 0kb file problem and I fixed this in ImageMagick. This will be fixed in the next release of Magick.NET.
The other temporary file looks like pixel data. Is it possible that this was from a crash that happened earlier? Please let me know if you can create a reproducible situation like the 0kb example.
