file:///Macintosh HD is an invalid path.  In POSIX/URL land, the boot volume's name is nowhere to be seen; POSIX file "/" and POSIX file "file:///" both refer to HFS file "Macintosh HD:" (or whatever your boot volume's name is).

OMM (10.6.3), the indirect version with the variable works fine.

Hi Mark,

I don't get your suggestion to work:

tell application "System Events"
try
set myURL to "file:///Macintosh HD/Users/Thomas/Desktop/Test.txt"
set myFile to POSIX file myURL
end try
set myFile to POSIX file "file:///Macintosh HD/Users/Thomas/Desktop/Test.txt"
log myFile
get POSIX path of myFile
end tell

results in

tell application "System Events"
get POSIX file "file:///Macintosh HD/Users/Thomas/Desktop/Test.txt"
--> error number -1728 from POSIX file "file:///Macintosh HD/Users/Thomas/Desktop/Test.txt"
(*file Macintosh HD:Macintosh HD:Users:Thomas:Desktop:Test.txt*)
get POSIX path of file "Macintosh HD:Macintosh HD:Users:Thomas:Desktop:Test.txt"
--> error number -1700 from «class posx» of file "Macintosh HD:Macintosh HD:Users:Thomas:Desktop:Test.txt" to reference

So the first problem is:

System Elends accepts
set myFile to POSIX file "file:///Macintosh HD/Users/Thomas/Desktop/Test.txt"
but not 
set myURL to "file:///Macintosh HD/Users/Thomas/Desktop/Test.txt"
set myFile to POSIX file myURL
which I find strange.

And then the result of the POSIX file command is
file Macintosh HD:Macintosh HD:Users:Thomas:Desktop:Test.txt
which obviously won't word because of the double "Macintosh HD".

Or am I doing it wrong?

Emmanuel's satimage osax solutions work OK, however.

POSIX file works with file URLs; in fact, the class of a POSIX file specifier is «class furl».

POSIX file "file://localhost/Users/richardr/Desktop/bevakad/NORRSÄTRASKOLAN_mall_
A4_2010/"

Should work as-is with System Events; add "as alias" if you intend to use it with the Finder.

satimage osax' absoluteurl command is good at that

does anyone know a way to locate a file by URL, such as

"file://localhost/Users/richardr/Desktop/bevakad/NORRSÄTRASKOLAN_mall_
A4_2010/"

and turn that into an alias/ posix file etc.

Preferably in vanilla AppleScript, as shell scripting seems to have some
encoding issues with decomposed/precomposed unicode characters
