Bill, what these error messages mean is that there are no files
whose name contains .txt in that folder.
I've just run a script and got this error:
"Finder got an error: Can't get Name of every document file of
every folder of alias
"BuiaBuio:Users:deivy:Desktop:Ex_Dtop_folder:" whose Name starts
with "Z"."
But if I change "Z" with "A", I get the desired result.
Hope this helps.

Deivy,

I ran a number of tests and documented everything that I found.
It turned out to be very interesting.
Thank You very much for all your insights, and help. I am gald
you did not give up.
I would have never figured out without all your help...

This is the folder hierarchy I used for the tests . You can see
that there are three files
whose name contains ".txt", and two files whose creator is
"MSIE", the main folder, and a subfolder
A_TEMP <-- folder
A_msie_file.html <-- Creator "MSIE"
A_text_file_01.txt <-- Creator ""
A_text_file_02.txt <-- Creator ""
B_TEMP <-- folder
B_msie_file.html <-- Creator "MSIE"
B_text_file.txt <-- Creator ""

-- ( b ) we are telling it to get the list as an "alias list"

caused by the fact that I got the list with "Sel", and processed it
with "aSel", a huge TYPO that I just caught...
