I would agree the AppleScript is just using the mac's Finder to duplicate a file to location… No need you can do this with the File object in javascript. It's the Folder object that does not have a copy method…

I had NOT noticed that behavior before now… Im rather rushed at the moment but your problem lies with the file paths passed by javascript… They are POSIX in style and unescaped so Finder will have no idea what to do with it. You can specify POSIX paths & files when working with Finder but you will need to change the AppleScript strings to do so…

Actually my task is copy the file and paste it in a destination folder, but the thing is it should not modify the date of creation.
While doing copy paste in javascript it modifies the current date to that file. It should not happen to my case.

It's a little bit late to answer -- two weeks have already passed -- but here is a function that I wrote to deal with this problem, it works both for Mac and Windows.

function MoveFile(myFile, myFolder) {
     if (!myFile instanceof File || !myFolder instanceof Folder || !myFile.exists || !myFolder.exists) return false;
     var myMovedFile = new File(myFolder.absoluteURI + "/" + myFile.name);
     if (File.fs == "Windows")  {
          var myVbScript = 'Set fs = CreateObject("Scripting.FileSystemObject")\r';
          myVbScript +=  'fs.MoveFile "' + myFile.fsName + '", "' + myFolder.fsName + '\\"';
          app.doScript(myVbScript, ScriptLanguage.visualBasic);
     }
     else if (File.fs == "Macintosh") {
          if (myFolder.fsName.match("Desktop") != null) {
               var myMacFolder = myFolder.fsName.replace(/\//g, ":");
               var myMacFile = myFile.fsName.replace(/\//g, ":");
               var myAppleScript = 'tell application "Finder"\r';
               myAppleScript += 'set myFolder to a reference to folder (name of startup disk & "' + myMacFolder + '")\r';
               myAppleScript += 'set myFile to a reference to file (name of startup disk & "' + myMacFile + '")\r';
               myAppleScript += 'tell myFile\r';
               myAppleScript += 'move to myFolder\r';
               myAppleScript += 'end tell\r';
               myAppleScript += 'end tell\r';
          }
          else if (myFolder.fsName.match("Documents") != null) {
               var myMacFolder = myFolder.fsName.replace(/\//g, ":");
               var myMacFile = myFile.fsName.replace(/\//g, ":");
               var myAppleScript = 'tell application "Finder"\r';
               myAppleScript += 'set myFolder to a reference to folder (name of startup disk & "' + myMacFolder + '")\r';
               myAppleScript += 'set myFile to a reference to file (name of startup disk & "' + myMacFile + '")\r';
               myAppleScript += 'tell myFile\r';
               myAppleScript += 'move to myFolder\r';
               myAppleScript += 'end tell\r';
               myAppleScript += 'end tell\r';
          }
          else {
               var myMacFolder = myFolder.fullName.replace(/\//, "").replace(/\//g, ":");          
               var myMacFile = myFile.fullName.replace(/\//, "").replace(/\//g, ":");
               var myAppleScript = 'tell application "Finder"\r';
               myAppleScript += 'set myFolder to folder "' + myMacFolder + '"\r';
               myAppleScript += 'set myFile to document file "' + myMacFile + '"\r';
               myAppleScript += 'tell myFile\r';
               myAppleScript += 'move to myFolder\r';
               myAppleScript += 'end tell\r';
               myAppleScript += 'end tell\r';
          }
          app.doScript(myAppleScript, ScriptLanguage.applescriptLanguage);
     }
     if (myMovedFile.exists) {
          return true;
     }
     else {
          return false;
     }
}

You are correct… Photoshop has no app.doScript()

Mine was just some typos.

Thank you.

I decided I don't care about the created data and just used javascript. It worked fine.

I still have no idea why the applescript wouldnt work for server folders for me but it's not a big deal.

Thanks
