Change link.filePath in InDesign

Question

Hello each other We have macOS as well as Windows in use and since InDesign does not use relative file paths, we have placed a symbolic link to the file server on Windows. But before saving the InDesign back to Windows, we want to run a script that adjusts the image paths back to the "Mac path". Now I have a script here that almost meets my requirements. Only it also checks if the links are missed as well as updates the links. But now I don't have any links on Windows and on the macOS clients I don't want to install the script, because only one person works with Windows. So I just wanted to create a simple script, which just stupidly and without logic rudimentary changes the path from (Attention example:) "SAMPLE" to "SMPLE". So a simple search and replace, but without relinking.I would probably then have an InDesign server process it that way. But now I have the problem that this property is read-only. I have also tried running the following, but to no avail:filePath.readonly = false; This is my script:var doc = app.activeDocument;
var links   = doc.links; //Erkennt alle Links
var counter = 0;

var PATH_FROM   = "Macintosh HD";
var PATH_TO     = "Windows";

for (var i = links.length -1; i >= 0; i--) {
	link = links[i];
	file_path = link.filePath;
	new_file_path = file_path.replace(PATH_FROM, PATH_TO);
	link.filePath = new_file_path;
	/*
    if (links[i].status == LinkStatus.LINK_MISSING) {
        new_file = new File(new_file_path);
        if ( new_file.exists ) {
            link.relink(new_file);
            link.update();
            counter++;
        }
        else {
            alert("Die Datei konnte nicht gefunden werden:
" + new_file_path);
        }
    }*/
} In InDesign I get the Error (filePath is a read-only property):Do you have any idea? I hope you can help me. Kind regardsNoel Bürgler

You're right Noel! Okay, here's a modified version that fits your use case I think. Let me know how you go.

    Reinit Links
    for Adobe Indesign 2022

    Use this when your file system has changed and current links are broken.
    Set `replaceThis` and `withThis` to re-align the file paths.

    This is different to Relinker because it doesn't require
    modified links to exist.
*/

function main() {

    reinitLinks(

        // the document to relink
        app.activeDocument,

        // in each link path, replace this string or a regex
        /SAMPLE/,

        // with this string
        /SMPLE/

    )


    function reinitLinks(doc, replaceThis, withThis) {
        var links = doc.links,
            counter = 0;

        for (var i = 0; i < links.length; i++) {
            var linkURI = links[i].linkResourceURI,
                newLinkedURI = linkURI.replace(replaceThis, withThis);
            links[i].reinitLink(newLinkedURI);
            if (linkURI != newLinkedURI)
                counter++
        }

        alert('Reinit ' + counter + ' out of '+links.length + ' links.');
    }

}

Hi Noel, this will give you an idea of how to do it I hope.
