Den funktionen finns inte i Mac OS X eller något program däri vad jag vet. Safari har det inte.
Detta Applescript visar tex att filer hemladdade från en webbsida i Safari inte får någon url som visar var filen kom ifrån.
tell application "Finder"
get properties of file "digga_mac.png" of folder "Hämtade filer" of folder "ola" of folder "Users" of disk "Wolverine"
end tell
--> {class:document file, name:"digga_mac.png", index:1, displayed name:"digga_mac.png", name extension:"png", extension hidden:false, container:folder "Downloads" of folder "Ola" of folder "Users" of startup disk, disk:startup disk, position:{-1, -1}, desktop position:missing value, bounds:{-33, -33, 31, 31}, kind:"Portable Network Graphics-bild", label index:0, locked:false, description:missing value, comment:"", size:7841, physical size:8192, creation date:date "söndag 18 oktober 2009 01.17.32", modification date:date "söndag 18 oktober 2009 01.17.32", icon:missing value, URL:"file://localhost/Users/Ola/Downloads/digga_mac.png", owner:"Ola", group:"Ola", owner privileges:read write, group privileges:read only, everyones privileges:read only, file type:missing value, creator type:missing value, stationery:false, product version:"", version:""}
Samma scriptkört på en fil hemladdad med Firefox returnerar i stort sett samma info.
