Batch Rename under menubar/tools can do all of the above… Very easy to use ( has regexp too ) Script could do all your folders in 1 go… Depending on your platform you could also do this outside of Bridge…

Learning to script is not something thats done overnight… Well for me it was/isn't… If you require lots of scripted solutions its worth while it can save you lots of time but theres a learning curve… If this is your only need then someone may help but you would need to supply more details… I don't have CS6 but that may or may not be a problem… What OS are you using and where are the folders all in the same directory?

Hello, I've put bridge as the script target for this although it isn't actually using Bridge scripting commands… Give it a try on a smaller selection and see if it works… I only tested with 4 folders of a dozen files each looks pretty close to what you asked although date is vauge… Created date, modified date todays date?

#target bridge
 
reNameFiles();
 
function reNameFiles() {
 
          var top = Folder.selectDialog( 'Please select the top level folder' );
 
          if ( top != null ) {
 
                    var crFiles, folders, countA, countB, i, j, date, newName;
 
                    folders = top.getFiles();
 
                    countA = folders.length;
 
                    for ( i = 0; i < countA; i++ ) {
 
                              if ( folders[i] instanceof Folder ) {
 
                                        crFiles = folders[i].getFiles( /\.CR2$/i );
 
                                        countB = crFiles.length;
 
                                        for ( j = 0; j < countB; j++ ) {
 
                                                            date = '120109_'; // You may need to change this…??????
 
                                                            newName = 'fguy_' + date + zeroPad( j, 4 ) + '_SF.CR2';
 
                                                            crFiles[j].rename( newName ); 
 
                                        };
 
                              };
 
                    };
 
          };
 
};
 
function zeroPad( n, p ) {
 
  var t = n.toString();
 
          while ( t.length < p ) { t = '0' + t };
 
  return t;
 
};
 

Was pottering about so I put some date options in and fixed my zero error…

#target bridge

reNameFiles();

function reNameFiles() {

     var top = Folder.selectDialog( 'Please select the top level folder' );

     if ( top != null ) {

          var crFiles, folders, countA, countB, i, j, date, newName;

          folders = top.getFiles();

          countA = folders.length;

          for ( i = 0; i < countA; i++ ) {

               if ( folders[i] instanceof Folder ) {

                    crFiles = folders[i].getFiles( /\.CR2$/i );

                    countB = crFiles.length;

                    for ( j = 0; j < countB; j++ ) {

                         //date = '120109'; // A hard coded String Date…

                         date = new Date(); // Today's Date

                         //date = crFiles[j].modified;  // File Modified Date

                         //date = crFiles[j].created; // File Created Date

                         date = getDateYYMMDD( date );

                         newName = 'fguy_' + date + '_' + zeroPad( j+1, 4 ) + '_SF.CR2';

                         crFiles[j].rename( newName ); 

                    };
               };
          };
     };
};


function zeroPad( n, p ) {

     var t = n.toString();

          while ( t.length < p ) { t = '0' + t };

     return t;

};


function getDateYYMMDD( d ) {

     var yy = String( d.getFullYear() ).substring( 2, 4 );

     var mm = d.getMonth() + 1;

     if ( mm < 10 ) { mm = '0' + mm };

     var dd = d.getDate();

     if ( dd < 10 ) { dd = '0' + dd };

     return yy + mm + dd;

};

As it stands the above will run-in bridge as target… To run it would be best just to use the ExtendScript Toolkit… This can be found…

HD/Applications/Utilities/Adobe Utilities - CS5/ExtendScript Toolkit.app

Just cut and paste from here into a new window and run… ( on a test folder first )

It should ask you to select a top level folder/directory…

It currently uses today's date but I also left other options behind comments… the // lines…

Any problems give us a shot back should be close to what you asked…

If you like it save it using the Toolkit… It's possible to add this to Bridge UI if wanted…

How or where the date part of the new name comes from is purely down to you… You didn't indicate that was the case that's why I asked and offered several possibilities… Sure if that is the case then it's easy enough to get the name of the parent folder and use that…
