@Gubbi Depending on which processor is being used to create your FlowFile from you source linux directory, you will likely have an "absolute.path" FlowFile attribute created on the FlowFile. absolute.path = /users/abc/20200312/gtry/ You can pass that FlowFile to an UpdateAttribute processor which can use NiFi Expression Language (EL) to extract the date from that absolute path in to a new FlowFile attribute Add new property (property name becomes new FlowFile attribute): Property: Value: pathDate ${absolute.path:getDelimitedField('4','/')} The resulting FlowFile will have a new attribute: pathDate = 20200312 Now you can use that FlowFile attribute later when writing to your target directory in S3. I assume you would use the putS3Object processor for this? If so, you can configure the "Object Key" property with the following: /Users/datastore/${pathDate}/${filename} NiFi EL will replace ${pathDate} with "20200312" and ${filename} will be replaced with "gyyy.csv". Hope this helps you, Matt
