How can I batch a huge bunch of wmf to ai in multiple subfolders?

I am interested, but for Adobe Illustrator 2024, the script no longer work, anyone can help to advise?? Many thanks

So, this is a super old thread, but it came up in google almost at the top for what I was looking for, and it put me on the right track immediately, so I'm going to post the script I cobbled together that got all this done.

I have like... 10,000 wmf files? Somewhere in that range. These suck and you can't preview them in finder, so no one thinks to go through them (opening 1 by one), so this time when I was charged with finding some clipart, I decided to see if I could find a way to convert them all to .ai so finder can give me neat little previews.

Larry's script worked perfectly, but then, like OP, I was left unsatisfied by the artboard's size. Carlos knew exactly what he was wanting and artboardRect was definitely the way to go, but he didn't spell out how to use it. So I went to hunting again.

Knowing no extendscript and my js skills limited to query, I somehow managed to cobble together a working script by adding in the 1 and only answer from this stack overflow post. And so here it is. Enjoy! If it breaks, I honestly can't help...

var folder = Folder.selectDialog("Select Source Folder..."); // select folder

if (folder==null) {

    var files = find_files (folder, ['.wmf']);

          var fileCount = files.length; // count them

          if (fileCount>0) {

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

            var idoc = app.open(files);

            var doc = app.activeDocument; 

            // Select all objects on the artboard

            doc.selectObjectsOnActiveArtboard();

            // Get the size of the art

            doc.artboards[0].artboardRect = [0, doc.selection[0].height, doc.selection[0].width, 0];

            // Get the active Artboard index

            var activeAB = doc.artboards[doc.artboards.getActiveArtboardIndex()];

            var artboardBottom = activeAB.artboardRect[3];

            activeAB.position = (doc.selection[0].position[0], doc.selection[0].position[1]); 

            // Get the active Artboard index

            var activeAB = doc.artboards[doc.artboards.getActiveArtboardIndex()];

            // Get the Height of the Artboard

            var artboardBottom = activeAB.artboardRect[3];

            // The page item you want to move. Reference it how you will. This just

            // obviously grabs the first pageItem in the document.

            var myPageItem = doc.pageItems[0];

            // Here is where the magic happens. Set the poition of the item.

            // [0,0] would be at the top left, so we have to compensate for the artboard

            // height. We add myPageItem's height for offset, or we'd end up BELOW

            // the artboard.

            myPageItem.position = [0, artboardBottom + myPageItem.height];

            var saveOpts = new IllustratorSaveOptions();

            saveOpts.pdfCompatible = true;

            idoc.saveAs( files, saveOpts );

            idoc.close();

                    }

        alert(fileCount + ' file(s) processed');

          }

          else {

                    alert("There are no Illustrator files in this folder.");

          }

}
