Another approach, if aliases are required, is to remember that the
contents of a folder *are* normally returned in alphabetical order. The
order's only spoilt when something happens within the folder. (Hence the
original question.) On my machines (Mac OS 9.2.1 and 8.6) it's possible
to force a reset by opening and shutting the folder. Thus:
tell application "Finder"
tell alias source1
open
close
try
set theList to (its every item whose file type is "TEXT") as
alias list
on error
set theList to (its first item whose file type is "TEXT") as
alias as list
end try
end tell
end tell
I'd be interested to know if this works for other people and whether or
not it's faster than looping.
