Nifi ListFile not listing files starting with "."

[#1]

We have file names that start with a dot (e.g. ".~tempfile.bin") that we are attempting to list with the ListFile processor.  We've tried setting the File Filter to an empty string, as well as various RegEx's (e.g. ".*") and it will not list file names starting with a dot.  As soon as we remove the starting dot from the file name, it lists the files.  Any ideas on how to list these files starting with a dot?

Files that start with a dot are considered to be "hidden files" in Linux.

To read those files with the ListFile processor, simply set Ignore Hidden Files to false.

Perfect, that did it.  Thanks for your help @araujo!
