Hello @HoangNguyen,  If I do not understand wrong, what you want is not possible.  ListFile does not support incoming FlowFile as an source.  To do that, you will need to use variable registry.  Look here: Display Name: Input Directory API Name: Input Directory Description: The input directory from which files to pull files Supports Expression Language: true (will be evaluated using variable registry only) https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-standard-nar/1.9.2/org.apache.nifi.processors.standard.ListFile/index.html Looking on that, FetchFile will do what you need:  Display Name: File to Fetch API Name: File to Fetch Default Value: ${absolute.path}/${filename} Description: The fully-qualified filename of the file to fetch from the file system Supports Expression Language: true (will be evaluated using flow file attributes and variable registry) https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-standard-nar/1.9.2/org.apache.nifi.processors.standard.FetchFile/index.html ...
