To restore a backup of your configurations, not many steps are necessary. If you have made a copy of the “config” folder in .barcodeeshipping as described in HERE, then all you need to do is replace the original folder with the backup.
The config folder and the backup folder must both be in the following directory:
Replace USERNAME with your username in your system
Copy the backup of your config folder into the .barcodeeshipping folder
Delete the old config folder and then copy the backup config folder there. The backup was restored so successfully.
