How to create a subfolder and save files (without open the FileSystem)

Adobe XD UXP Plugin API
#1

Hey everybody,

I would like to create a subfolder, in the folder the user has choosen for export and save some files.
But the name of the subfolder and the name of the files will be generated automaticly - so the user only have to choose the “mainfolder” in the beginning.

Unfortunately, I can’t even create a subfolder…=(

(And if you know a way to do this without open the FileSystem again I would love to know that, too)

Happy about any help here!! :see_no_evil:

I’m using this to check for a subfolder and create it if it doesn’t exist. You have to pass in the folder the user has selected and it must be a sub folder. It doesn’t support nested folders.

/**
 * Gets a reference to a subfolder from a folder object. Creates it if it doesn't exist.
 * Does not support nested directories at this time
 * @param {File} folder file of type folder  
 * @param {String} subfolderName name of sub folder
 * @param {Boolean} create if true creates the directory if it doesn't exist
 * @returns {File|Error} returns the folder or an error object
 */
async function getSubFolder(folder, subfolderName, create = true) {
  var subfolder = null;

  try {
    subfolder = (await folder.getEntries()).find(entry => entry.name.includes(subfolderName));

    if (subfolder==null || subfolder.isFolder==false) {
      if (create) {
        subfolder = await folder.createFolder(subfolderName);
      }
    }
  }
  catch(fileError) {
    return fileError;
  }

  return subfolder;
}

/**
 * Returns true if a subfolder exists
 * @param {File} folder file of type folder  
 * @param {String} subfolderName name of sub folder
 * @returns {Boolean} returns true if folder exists
 */
async function checkSubFolderExists(folder, subfolderName) {
  var subfolder = null;

  try {
    subfolder = (await folder.getEntries()).find(entry => entry.name.includes(subfolderName));

    if (subfolder!=null && subfolder.isFolder) {
      return true;
    }
  }
  catch(fileError) {
    log(fileError);
  }

  return false;
}
