Question

Answer 1

This requires Photoshop CS3 or better.
Copy and paste the script into ExtendScript Toolkit
This gets installed with Photoshop and can be found:-
PC: C:\Program Files\Adobe\Adobe Utilities
Start Bridge
Edit - Preferences - Startup Scripts
At the bottom click the "Reveal Button" this will open the folder where the script should be saved.
Close and restart Bridge.
Accept the new script.
To Use:
Select the documents
Tools - "Add FileName to Title"
#target bridge  
   if( BridgeTalk.appName == "bridge" ) { 
FT = MenuElement.create("command", "Add FileName to Title", "at the end of Tools");
FT.onSelect = function () {
   AddFilenameToTitle();
function AddFilenameToTitle(){
var thumbs = app.document.selections;
if(!thumbs.length) return;
if (ExternalObject.AdobeXMPScript == undefined)  ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
for(var a in thumbs){
var selectedFile = thumbs[a].spec;   
var Title = decodeURI(selectedFile.name).replace(/\.[^\.]+$/, '')
      var myXmpFile = new XMPFile( selectedFile.fsName, XMPConst.UNKNOWN, XMPConst.OPEN_FOR_UPDATE);
  var myXmp = myXmpFile.getXMP();
        myXmp.deleteProperty(XMPConst.NS_DC, "title");
        myXmp.appendArrayItem(XMPConst.NS_DC, "title", Title, 0, XMPConst.ALIAS_TO_ALT_TEXT);
        myXmp.setQualifier(XMPConst.NS_DC, "title[1]", "http://www.w3.org/XML/1998/namespace", "lang", "x-default");
        if (myXmpFile.canPutXMP(myXmp)) {
        myXmpFile.putXMP(myXmp);
         myXmpFile.closeFile(XMPConst.CLOSE_UPDATE_SAFELY);
