Lorenzo,

The error is that you cannot and must not put a slash in a filename in OS X.
(Yes, I know that some things in the past have done so, but this has from
the Public Beta been a bad move.)

This is because the slash is the BSD separator in paths. OS X is unable to
distinguish between a file called this/that and a file called that in the
folder this.

The same applies to OS X's other separator (from its Mac heritage), the
colon - it also causes confusion in paths.

If you want to verify this, try editing a file name in the Finder (in Jaguar
or later - 10.0 and 10.1 did not object so strongly!) to contain these
characters.

One other character to avoid is a trailing hash # followed by anything that
could appear to be hexadecimal, e.g. this#dead - this is a bug affecting
10.2 and 10.2.1, though, and not intentional.

Howard.
