InDesign Unused Images Notifcation

Hi Eddie,

It might be a bit overkill but give this code a try......Note: currently the script looks into the Links folder and will return the names of any files not placed or linked to the active documnet from that location,  you will need to modify the file path for Windows and where your files reside.

myDocFolder = app.activeDocument.filePath;
var myLinkAssetsFolder = Folder(myDocFolder.fsName + "/" + "Links"); 
var myFiles = myLinkAssetsFolder.getFiles();

function myGetFileNames(){
    var myFileNames = new Array;
     for (var i = 0; i < myFiles.length; i++){  
      myFileNames.push(myFiles[i].name);
  }
   
      return myFileNames;
  }

var myLinkName = new Array();
myLinks = app.activeDocument.links;
for(var i=0; i < myLinks.length; i++){
myLinkName.push(myLinks[i].name);
}

var fileNames = myGetFileNames();
var myLinks = myLinkName;

function myGetFilesToPlace(){
  var myLinkedNames = myLinks;
  var myFileList = new Array ();
   for (var i = 0; i < fileNames.length; i++){
    if(!String(myLinkedNames).match("\\b"+fileNames[i]+"\\b")) {   
      myFileList.push(fileNames[i]);

    }
 }
    return myFileList;
}
var filesToPlace = myGetFilesToPlace();
filesToPlace = (String(filesToPlace).replace(/%20/g, " "));
alert(filesToPlace)

Regards,

Mike
