      baseFolder: string,
      folderList: string[] = []

      const folders: string[] = fs
        .readdirSync(baseFolder)
        .filter(file => fs.statSync(path.join(baseFolder, file)).isDirectory());
      folders.forEach(folder => {
        folderList.push(path.join(baseFolder, folder));
        getAllSubFolders(path.join(baseFolder, folder), folderList);

      return folderList;
    };
    export const getFilesInFolder = (rootPath: string) => {
      return fs
        .readdirSync(rootPath)
        .filter(
          filePath => !fs.statSync(path.join(rootPath, filePath)).isDirectory()
        )
        .map(filePath => path.normalize(path.join(rootPath, filePath)));
    };
    export const getFilesRecursively = (rootPath: string) => {
      const subFolders: string[] = getAllSubFolders(rootPath);
      const allFiles: string[][] = subFolders.map(folder =>
        getFilesInFolder(folder)
      );
      return [].concat.apply([], allFiles);
    };
