It would be a lot easier to diagnose if you'd share actual error messages; even native English speakers have trouble understanding "blahblah..." :-)

There is an internal File Manager data type (the FSRef) that's currently
recommended for storing file references, but you can only create FSRef
structures that point to existing files - you can't make one that points
to a file that doesn't exist, even though a pathname can. Aliases are
the same way, as many scripters have noted.


AppleScript uses FSRefs internally in some places, so at some point,
trying to refer to an actual "file" object may fail if the file does not
exist. I can't tell you exactly when or now, and I don't know if this
is your "can't make fref from POSIX blahblah" problem, but it's worth
noting.
