This begs the obvious question:
Are these dubious files created with Amiga browsers on Amiga hardware? More importantly, are these files deleted when you try to delete them? What about under "Amiga" emulation? I think in the case of Faux Amiga, yes, because the "Amiga" is just a layer on top of all that windoze bloat and it is, afterall, a Pee See.
