If you are having fully qualified filename with the directory information in your flow then you can use Fetch File Processor as this processor accepts incoming connection and pass the attributes(directory/filename) in File to Fetch Property to pull the File into the flow.

If you are not having fully qualified filename then we need to list all the files in the directory by using ExecuteStreamCommand processor by passing the dynamic generated directory name as an argument to list all the files in the directory then using Fetch File processor you can pull the required files into data flow.

Please refer to this link i have explained how to use ExecuteStreamCommand processor to list all the files in the directory,in addition to filter only the required filenames you can use RouteOnAttribute Processor before FetchFile Processor.
