AppleScript - 獲取文件夾中唯一文件的名稱？

Question

下面的AppleScript代碼獲得最後添加的文件，

tell application "Finder" 
    set latestFile to item 1 of (sort (get files of (path to downloads folder)) by creation date) as alias 
    set fileName to latestFile's name 
end tell

但是，如果該文件夾中只有一個文件失敗。如何解決這個問題？

Answer 1

該腳本應該與一個文件一起使用。但是如果有沒有文件，則會報錯。

您可以用try塊

tell application "Finder" 
    try 
     set latestFile to item 1 of (sort (get document files of (path to downloads folder)) by creation date) as alias 
     set fileName to latestFile's name 
    end try 
end tell
