[FBD]

This script checks if files in the download list already exist in their configured download folder (or additional folders) and disables or removes the links without having to start the downloads.

Script is intended to be triggered by a toolbar button named "FileCheck" which has to be added for the script to work.

Spoiler:

// Check if files in download list already exist and disable or remove link without starting downloads (FBD)
// Trigger : "Toolbar Button Pressed"
// Toolbar Button Name: "FileCheck"

// Uncomment if you know what you're doing
// disablePermissionChecks();

if (name == "FileCheck") {
    var myFilePackage = getAllFilePackages();
    var folders = [];
    var report = [];

    // Uncomment to ADDITIONALLY check if file exists in these folders
    // folders.push("/media/download","D:/Downloads","C:/Downloads2");

    var myDownloadLinks = getAllDownloadLinks();
    for (a = 0; a < myDownloadLinks.length; a++) {

        var link = myDownloadLinks[a];
        var myFilePackage = link.getPackage();
        var linkName = link.getName();
        
        var allfolders = folders;
        allfolders.push(myFilePackage.getDownloadFolder()); // regular download folder

        allfolders.forEach(function(folder) {
            // uncomment to ignore disabled links
            //if (!link.isEnabled()) return;

            var file = getPath(folder + "/" + linkName);
            if (!file.exists()) return;
        
            report.push("Package \"" + myFilePackage.getName()
                        + "\" Folder: \"" + folder + "\""
                        + "\" File: \"" + linkName + "\""
                        );

            // Deactivate Link
            link.setEnabled(false);
        
            // Uncomment to also remove link from download list
            // link.remove();
        });
    }
    
    // comment this if you don't want to see a report
    if (report.length > 0) {
        setAdvancedAlert(true);
        alert("The following links have been disabled because the files already exist:\n\n" + report.join("\n"));
    } else {
        alert("Check completed. No existing files found.");
    }
