The application notifies that the partition/drive of your hard disk (where the destination folder is located) is almost full. You need to delete some files in order to make the notification disappear. You can do this manually or use a disk cleaner utility from the database of Software Informer. If the drive is not almost full, try updating the Ummy Video Downloader utility to the latest version. If the issue persists, contact the support team using
email@example.com email address.
