Today, I will discuss about the configurations files which are newly introduced in Pentaho version >8. First of all, if you see in Pentaho version greater than 8, S3 file input and S3 file output components, Access Key and Secret Key variables are removed. See the below SS.

Below are the steps to be performed in windows Machine.

1. create folder inside C:/Users/user/.aws
2. In order to create .aws folder , give folder name as .aws. then .aws folder gets created.
3. Inside .aws folder, create files config and credentials without any extension.
4. In credentials file, below should be the content . Remember to put access and secret key values.
[default]
aws_access_key_id=Access_key_value
aws_secret_access_key=Secret_key_value

5. In config file, below should be the content. Here , you need to give region number as per AWS Region configured. Map your region as per URL(https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html). Mention the value of output accordingly.
[default]
region=us-east-1
output=csv

6. See the below SS of the files which i have configured in my local Machine.
