Apple

I'm working on a small Folder Action Script, whose second line looks like (exactly how I learned from the AppleScript Language Guide):

if (the file ":Index" exists) then

Bernhard,

:Index

Is not a valid file reference, which may be why you're getting that particular error.

AppleScript needs the full path:

file "hdName:dir:filename"

works, but

file ":filename"

won't work.

Also, the most reliable way to determine if a file exists in appleScript is to attempt a coersion to alias:

try

set myFile to "hdName:dir:filename" as alias

set fileExists to true

on error

set fileExists to fale

end try

HTH,
