EMS SQL Backup uploads files to the 'Apps/EMS SQL Backup' folder in Dropbox by default. If you need to store backup files in its subfolder, set the relative path in this field. If the specified folder doesn't exist, it will be created automatically on uploading the files. Use '/' as a path separator. For example, if you set 'backups/Adventure Works' in this field the files will be uploaded to 'Apps/EMS SQL Backup/backups/Adventure Works'.
