How to multiple get files [solution]

[bombkiml]

const jsftp = require("jsftp");
var async = require("async");

const dir = "./srcFolders";
const save_to = "localFolder";

const Ftp = new jsftp({
    host: "192.168.xx.xxx",
    port: "",
    user: "user_access",
    pass: "secret_password",
});

gatherFiles(dir) {
    return new Promise(function (resolve, reject) {

      Ftp.ls(dir + "/*", function (err, res) {
        if (err) reject(err);
        var files = [];
        res.forEach(function (file) {
          files.push(file.name);
        });
        resolve(files);
      });

    });
};

this.gatherFiles(dir).then((files) => {
        async.mapLimit(files, 1, (file, callback) => {


            // multiple save delay (needed)
            setTimeout(() => {
              // Save to local
              Ftp.get(dir+ file, save_to.concat("/" + file), (err) => {
                if (err) {
                  console.error("There was an error retrieving the file.", err);
                  callback(err);
                } else {
                  console.log("  - Saved>>", file);
                  callback();
                }
              });
            }, 1000);


          }, (err, res) => {
            if (err) {
              console.log(err);
              console.log("Save file error is Break!!!");
            }
            console.log("Save completed");
          }
        );
  });
