I have similar problems with the Finder and variables, which I don't really understand nor know how to circumvent.

Hey Thomas,

This is not a variable problem.  What's happening is that the Finder won't create posix paths; it is more comfortable with Finder references and aliases.

AND

What Yvan said.

set fPosix to "/Users/chris/test_directory/file.txt"
set fAlias to alias "Thor:Users:chris:test_directory:file.txt"

set fPosixFile to (POSIX file fPosix)
set fPosixFileFlag1 to fPosixFile exists --> true

tell application "Finder"
set faFlag to fAlias exists --> true
set fpFlag to fPosix exists --> false
try
set pfFlag to (POSIX file fPosix)
on error e
set pfFlagError to e --> Finder got an error: Can’t get POSIX file "/Users/chris/test_directory/file.txt".
end try
set pfFlag to fPosixFile exists --> true
end tell

Other parts of the System are more agnostic about alias, posix file, path string, but you have to experiment a bit to discover how much.

You can however do something like this if you need to:

set fPosix to "/Users/chris/test_directory/file.txt"

tell application "Finder"
tell AppleScript to set pfFlag to (POSIX file fPosix)
end tell

I generally prefer to work with aliases, and the Finder also supports alias lists which can be operated on en mass.

Chris
