What is the difference between 1) open file object and 2) open object in applescript. For example, I got an error "Can't make some data into the expected type." for the following code. tell application "Finder" set Xpath to "MacBookProHD:Users:tom:Music:" set cueFile to (Xpath & "test.cue") end tell tell application "Toast Titanium" activate open cueFile end tell However, there is no error with tell application "Toast Titanium" activate open file cueFile end tell For TextWrangler, either way works fine. I'm confused.
