Click on Choose File, then navigate to your .gwbk file. By default, all your Gateway backup files are saved in your Downloads folder unless you select another folder location.
If you have downloaded a Gateway Backup and are trying to Restore it, you must have a .gwbk file type. Often, Internet Explorer will change the extension from .gwbk to .zip when the backup is downloaded. The correct format for a downloaded backup is "Ignition-backup-YYYYMMDD-HHMM.gwbk" where YYYYMMDD-HHMM is the timestamp. Or "" if you are restoring a challenge file from the Inductive University.
Choose your Ignition backup file (
.gwbk), and click Open.
