I am curious how I might go about creating an applescript that allows
the user to use a file browser to select a folder, and then dives into
that folder processing the files and subfolders. I found this
excellent Subroutine in the "AppleScript: Essential Subroutines" page
in the Apple site:
http://www.apple.com/applescript/guidebook/sbrt/pgs/sbrt.09.htm
This piece of code does exactly what I want, except it requires files
and folders to be dropped on it because it is a droplet. How might I
adapt this to make it so the user can set the folder to start with
instead of dropping it on the script?
FYI: I have tried adding:
set this_folder to (choose folder with prompt "Pick the folder
containing the files to process:") as string
tell application "System Events"
set these_items to every file of folder this_folder
end tell
But I get a: NSCannotCreateScriptCommandError when I try to run the
script. (When I added the above to the script, I removed the "on open
these_items" and "end open".
thanks

-- eg: {"PICT", "JPEG", "TIFF", "GIFf"}
property type_list : {}
-- since file types are optional in Mac OS X, -- check the name
extension if there is no file type
-- NOTE: do not use periods (.) with the items in the name extensions
list
-- eg: {"txt", "text", "jpg", "jpeg"}, NOT: {".txt", ".text", ".jpg",
".jpeg"}
