Script: insert folder name as text on open or saving document

Thanks @CarlosCanto 

Took me a while to get it right, but it is going back 3 folders now
<Folder>>Proof>Files>File.ai

And it returns <Folder> into the text marked on the page with Attributes through text marked with a Note

I've added this code to another script that saves the file and updates date/time and it seems to work quite well.

Code I came up with to fetch the folder name

// Main Code [Execution of script begins here]
try {
    if (app.documents.length > 0) {
        var sourceDoc = app.activeDocument;
        
        // Get the file path of the Illustrator document
        var filePath = sourceDoc.fullName.fsName;
        
        // Get the parent folder name
        var parentFolderName = getParentFolderName(filePath);
        
        // Log the retrieved parent folder name
        $.writeln("Retrieved Parent Folder Name: " + parentFolderName);
        
        // Update the text object with the folder name
        updateTextWithFolderName(parentFolderName);
        
        // Your existing code to save the document as PDF
        // ...
    } else {
        throw new Error('There are no documents open!');
    }
} catch(e) {
    alert(e.message, "Script Alert", true);
}

/** Retrieves the parent folder name from the file path.
    @param filePath The file path of the Illustrator document.
    @return The parent folder name.
*/
function getParentFolderName(filePath) {
    var pathComponents = filePath.split("/");
    var folderName = null;
    if (pathComponents.length > 3) { // Ensure there are enough components in the path
        // The parent folder is the fourth-to-last component in the path
        folderName = pathComponents[pathComponents.length - 4];
    }
    return folderName;
}

/** Updates the text object with the folder name.
    @param folderName The name of the folder.
*/
function updateTextWithFolderName(folderName) {
    var doc = app.activeDocument;
    var textObjectFound = false;
    for (var i = 0; i < doc.pageItems.length; i++) {
        var item = doc.pageItems[i];
        if (item.note === "Folder") {
            textObjectFound = true;
            item.contents = folderName;
            break; // Exit the loop once the folder name is updated
        }
    }
    if (!textObjectFound) {
        alert("Text object labeled 'Folder' not found in the document.");
    }
}
