Quick copy-paste folders/layers into another file?

Ultimately the task does not seem interesting enough (or explained well enough) to write a Script for Folder-selection etc. but looking for an image with the same three-digit-number in its name as the open image in a neighboring folder and duplicating all Layers to that should be done with the following. 

// if three-digit-number in file name and only two folders side-by-side open image from other folder with same three-digit-number in name;
// duplicate all layers to the second image;
// 2023, use it at your own risk;
if (app.documents.length > 0) {
    var myDocument = activeDocument;
    var theID = getDocumentId ();
    var theFolder = File(myDocument.fullName).parent;
    var theTopFolder = theFolder.parent;
    var theFolders = theTopFolder.getFiles(getFolders);
// the folder;
    if (theFolders.length == 2) {
        for (var m = 0; m < theFolders.length; m++) {
            var thisOne = theFolders[m];
            if (String(thisOne) != String(theFolder)) {
                var theOtherFolder = thisOne
            }
        }
    };
// the three-digit-number;
    var theString = myDocument.name;
    var theRegExp =/[^\d]\d{3}[^\d]/i;
    var theString = String(("_"+theString).match(theRegExp));
    var theShortRegExp = /\d{3}/i;
    var theNumber = theString.match(theShortRegExp);
if (theNumber != null) {
// the other file;
    var theFiles = theOtherFolder.getFiles(/.psd/);
    for (var n = 0; n < theFiles.length; n++) {
        if (theFiles[n].name.match(theNumber) != null) {
            var theOtherFile = theFiles[n]
        }
    };
if (theOtherFile) {
    var theOtherDocument = app.open(File(theOtherFile));
    var theOtherID = getDocumentId ();

Even doing it manually for now could be made more enjoyable by using a script like this...
https://community.adobe.com/t5/photoshop-ecosystem-discussions/how-to-open-a-number-of-images-but-one-at-a-time/m-p/13794488

I haven't tested this particular one, but used one many years ago.

If you connect that script to a hotkey (or action hotkey that calls it), it can be configured so it each time saves/closes the current doc and loads the next file in a directory.  So no need to open a bunch at once, or be switching to your file manager. You'd basically be using two shortcuts and a click.

- next doc hotkey

- click where to paste

- paste

The hotkey will save and close and open the next one.

If the company trusts a commercial script more (or if it has extra options), maybe get this one on their dime... 😉

If it's as simple as you are showing, I don't think you need a script.

Supposing your source files are the same for each target file (that is the question...), you could use this kind of workflow...

- have your source document opened

- copy those folders (putting them on your clipboard)

- batch an action that opens each target doc, selects the layer you want the folders to go on top of (or the top layer), and Paste. Do your stuff or just Save and Close document. Batch then opens the next one and does it all over again...

If you want to make sure your clipboard is not harmed while doing other things, then you should have the action go and copy the folders everytime in your source doc.

If these folders are the same ones you want to apply to another document, you could maybe find a workflow that (re)links a Smart Object (which would link to that one document with these folders). I forgot exact details, but research the link or relink commands for those.

Also if the folders are the same (let's say your folders contain adjustment layers), you can sometimes do it the other way around: paste just your "photo" into that file, go through some Layer Comps with an action if you like, and each time save that variation (and do that in batch).

That's in case you can keep it simple. Your docs may be complex or require the folders to stay there...

That would seem to need Scripting – but unless you are already familiar with JavaScript this may be a bit steep (or one of the regulars find the task interesting enough to write a Script for it).  

In any case you should provide a small number of the corresponding file-pairs.
