Missing Links In Indesign ...

Worked for me https://www.marspremedia.com/software/indesign/links-relink-subfolders ... also if images are duplicated in subfolders you are notified to manually assign ... InD2023

For anyone that needs it, I've written this script. This script will search for any missing image files in the specified parent directory and all its subdirectories, and if it finds any it will attempt to re-link them. 

Simply replace "path/to/parent/directory" with your desired parent directory (keep the quotes), save the file as a .jsx file in the scripts directory and run it. for more info on how to do this, go here: https://helpx.adobe.com/indesign/using/scripting.html

// Replace "path/to/parent/directory" with the actual path to the parent directory
var parentDirectory = new Folder("path/to/parent/directory");

// Get the current document
var doc = app.activeDocument;

// Iterate through all the links in the document
for (var i = 0; i < doc.links.length; i++) {
  var link = doc.links[i];

  // Check if the link is missing
  if (link.status == LinkStatus.LINK_MISSING) {
    // Search all subdirectories within the parent directory for the missing file
    var missingFile = searchForFile(parentDirectory, link.name);

    // If the file is found, re-link it to the document
    if (missingFile) {
      link.relink(missingFile);
      link.update();
    }
  }
}

// Save the document
doc.save();

/**

 * @9397041 {Folder} directory - The directory to search in.
 * @9397041 {string} fileName - The name of the file to search for.
 * @Returns {File} The file if found, or null if not found.
 */
function searchForFile(directory, fileName) {
  // Get a list of all files within the directory
  var files = directory.getFiles();

  // Iterate through each file
  for (var i = 0; i < files.length; i++) {
    var file = files[i];

    // If the file is a directory, search within it recursively
    if (file instanceof Folder) {
      var result = searchForFile(file, fileName);
      if (result) {
        return result;
      }
    }
    // If the file is the one we're looking for, return it
    else if (file.name == fileName) {
      return file;
    }
  }

  // If the file was not found, return null
  return null;
}

You need to start packaging your jobs as part as your workflow. this is the only way maintain all of your files together with the indesign document no matter where things move, share drives or who is working on it.  Its a free feature that takes seconds to run. Go to File>> package and run it after you link your files. after you do this. if you need to add graphics to your layout, you can save them in the links folder that is now created with your package files, or re-package and replace.

You will have a better organization and make your life easier if you start packaging your files.

Hi,

You would need to re-link the designs. You can also re-link the entire folder.
