Was in a hurry to geek-out, didn't fully read yours or Nick(?)'s
Tis a fucker though the way windows file permissions only seem to function when the end result is user annoyance, any operation which is stupid or dangerous, and they step aside.
Unix file permissions are far better, no surprise there then since windows is based on DOS, which is based on CPM, which was "unix for the terminally stupid", and had about 30 commands, instead of the hundreds found on even fairly basic unix systems.
That's why the slashes go the other way in the MS world, to make it look different.
The bit that always amuses me, is that the official story is that QDOS (Quick and Dirty Operating System), which was later renamed as MSDOS.....was supposedly ripped off via reverse engineering[1] CPM. However, several CPM hackers [2] state that they'd tried using undocumented features and hacks on QDOS and they worked. While it's possible that one might reverse engineer an undocumented feature if you had found it and knew it was there, this simply isn't the case for hacks, which typically depend on the precise architecture of the code. In other words, this strongly implies that QDOS was simply a slightly altered and stolen version of CPM. In other words Windows is a graphical shell for an aging backend based on a stolen copy of "'nix for 'tards", any wonder it barely works.
Ooooops, I've ranted again.
I should be kinder to windos these days, my Windows Indego, is actually quite good, and quote stable, and I'd reccommend it over any official release. Of course when stuff goes wrong it's still unspeakably hard to figure out the problem ("an error has occurred, please clck here for more information" (clickety) "No more information is available"..... I'd prefer "I've crapped them again", at least that doesn't imply MS know what's wrong with their bugfest). Thankfully it breaks a lot less than any official release I've used.
[1]Don't mind this, after all, all non-IBM PC's are a product of reverse engineering, and there's a few Linux apps like that too.
[2] That's Hackers as in the correct definition.
