    Renaming files in a book

    heatherb555 Level 1

      Hi everyone,


      I need to rename files in a book, but from within the book. A Save as... won't update the cross refrences.


      I see an fcode for this (FCodes.KBD_BOOKRENAMEFILE), but I've been advised not to rely on these types of shortcuts.


      I don't see anything else documented in the Scripting Guide. Does anyone else have any other suggestions?


      Thanks so much!

          Sadly I don't have an answer to this question and I'm hoping to bump this up to see if anybody out there now has an answer.


          I've been looking into it and I have found examples in ExtendScript suggesting (for illustrator):


          var myfile = File.openDialog( 'select your AI file…' );

          myfile.rename( 'NEW.ai' );


          However I want this to be done automatically without opening a dialog.

          I can programmatically cycle through book components and can skip over folders and groups. I'm hoping to rename files to a naming structure based upon the top level element name and it's attributes (all of which I have already done). Now all I need to do is to take the name that has been calculated and replace the old name with it (Similar to how you can simply click on a file in the book and rename it). Any thoughts or suggestions would be greatly appreciated.


          The following is what I have been trying so far:


          function SaveFM(Item) {

               var NewName,


               Filetype = Item.Name.split(".").pop();


               //NameEncoder returns a string containing the new file name (no path or file type);

               NewName = NameEncoder(Item, AbbrList) + "." + Filetype;


               //If the component being checked is a folder or a group the name returned is "Skip." Files such as TOC or Indexes will return starting with "XXX" to allow them to be skipped as well.

               if (NewName.substring(0, 4) !== "Skip" && NewName.substring(0, 3) !== "XXX") {

                    //I have tried the following, using .Save with the full file path, retProps, and saveProps (though these would probably create a new file which is not the end goal). All of them are throwing an error and I'm not sure what I am doing wrong.

            Hi Heather,


            A book component has a Name property that you can use to rename the file. The name will show in the book window as a relative path from the book, but when setting the Name property, you use an absolute path.


            Of course this only changes the name in the book window. To rename the file on disk you can use ExtendScript's File object methods. Then, you will have to open all of the other components in the book and resolve any cross-references that used to point to the renamed document. Basically, you are doing what the built-in command does, but via scripting. If you need help with the individual steps, please let me know.

              Hi Rick,


              Thanks for the info. I've gotten some code that creates an array of all the files in my book, their old names, and their new names.


              However, the "Name" quality of the files are grayed out and for some reason don't change. I can easily change the "Label" and the "PrintFileName" (both of their icon's are blue). Is there some other way I should be doing this?


              I've attached the section of my code that is doing the renaming:


                  for (var i = 0, len = FileArray.length; i < len; i++) {

                      ThisFile = FileArray[i][0];

                      OldName = FileArray[i][1];

                      NewName = FileArray[i][2];

                      ThisFile.Name = NewName;

                      ThisFile.Label = NewName.split(".").shift(); //since the label does not contain a file type

                      ThisFile.PrintFileName = NewName.split(".").shift() + ".ps" //since file type is .ps

                Just following up for anybody else who might need this in the future.


                My hangup was that pulling files from the book itself created Doc objects, not File objects (beginners mistake, you hate to see it). Anyway, here are some of the functions that I came up with to handle this task for anybody who needs it. Please be warned, this is quite literally my first ExtendScript project so this may not be the most efficient way to have done this (I'm always open to constructive criticism from those more experienced than myself). I know I went overkill with notes in the code, that was requested by colleagues who know less about code than I do so that if I were no longer employed for some reason another person could come in and understand exactly what the code was doing.



                function fileNameReplacer(FullArray, CodeBook, BookFile) {
                    /*The fileNameReplacer steps through all of the files in the book looking for those who need to be renamed.
                        The function first renames all of the files, and then cycles through each file's Crossreferences and updates the
