Get indd files from folder and its subfolders

[Martin PH]

I messaged brianp311 asking about my problem about gettinng indd files from folder and its subfolders  and I want to make his reply public as a reference for others who wants to do the same.

Here is the template code:

var main = function() {
    var mainFol = Folder.selectDialog("Choose the main folder");
    recursiveFunc(mainFol, mainFol); 
}

var recursiveFunc = function(folder, mainFol) {
    var inddRx = /\.indd$/gi;
    var allFiles = folder.getFiles();
    var doc;
    for (var i = 0; i < allFiles.length; i++) { 
        if (allFiles[i].hidden) continue;
        if (allFiles[i] instanceof Folder) { 
            recursiveFunc(allFiles[i], mainFol);
            continue;
        }  
        if (inddRx.test(allFiles[i].name) { 
            doc = app.open(allFiles[i]);
            doc.save(File(mainFol.fsName +"/" + allFiles[i].name));
            doc.close(SaveOptions.NO);
        }
    }
}

 Thank you for this, Brian!

Thanks for sharing!
Here's a similar function — see How to find all indd-files inside subfolders — and some other useful snippets.

Hi Martin,

I found that in very complex folder hierarchies with a lot of files and folders it could be an advantage to first do one loop with a recursive function to gather all the folders first, store them in an array and then do another loop on the stored folders of the array to get the files.

I have modified your code as below.

var main = function () {
    var mainFol = Folder.selectDialog("Choose the main folder");
    recursiveFunc(mainFol, mainFol);
}

var recursiveFunc = function (folder, rootDir) {
    var inddRx = /\.indd$/gi;
    var allFiles = folder.getFiles();
    var doc;
    for (var i = 0; i < allFiles.length; i++) {
        if (allFiles[i].hidden) continue;
        if (allFiles[i] instanceof Folder) {
            recursiveFunc(allFiles[i], rootDir);
        }
        else if (inddRx.test(allFiles[i].name)) {
            try {
                doc = app.open(allFiles[i]);
                doc.close(SaveOptions.YES, new File(rootDir + "/" + doc.name));
            }
            catch (e) {
                //File may be in upper version or corrupt
            }
        }
    }
}

Thanks. Just FYI the request was to save all files back up to the root folder.

Thank you for notice, I have upated the code in my post.

Here is mine:

function getFiles(folder, subfolders, extension) {
    // folder = folder object, not folder name.
    // subfolders = bool, true = include subfolders.
    // extension = string, extension to include.
    // extension undefined = any.
    // Combine multiple extensions with regex OR, i.e. indd|tif|txt
    // Ignores hidden files.
    var d = [];
    var f;
    var files;
    var i;
    var pattern = new RegExp("\." + extension + "$", "i");
    files = folder.getFiles();
    for (i = 0; i < files.length; i++) {
        f = files[i];
        if (f instanceof Folder && subfolders) {
            // Recursive (function calls itself).
            d = d.concat(getFiles(f, subfolders, extension));
        } else if (f instanceof File && !f.hidden && (extension == undefined || pattern.test(f.name))) {
            d.push(f);
        }
    }
    return d;
}

// USAGE

var files = getFiles(folder, true, "indd");

for (var i = 0; i < files.length; i++) {
    // Do something with each file.
}
