I have a line of script as follows:

set Imagepath to POSIX file thePath as alias

When thePath points to a file in my user folder, the above returns the correct alias so I can open the file.

When thePath points to

… the script returns the following error:

Is there a way around this? I just want to open the file in Photoshop…

Thanks

The path has spaces in it that you should escape or use quoted form of…

This works for me:

set tPath to "/private/tmp/"
set F to (POSIX file tPath) as alias

Not for you? Are you an admin user?

My fault. The tmp directory did not exist. If I have a path to a file in thePath, how can I test if the file referenced by thePath exists, before forcing the alias?

#4 
set tPath to "/private/tmp/"
try
set F to (POSIX file tPath) as alias
on error
do shell script "mkdir /private/tmp"
set F to (POSIX file tPath) as alias
end try

Thanks for the help, have included this to check for file before forcing alias:

set msg to false
tell application "Finder" to if exists thePath as POSIX file then set msg to true

If msg is true, I can force an alias. Otherwise, the script generates an error.
