Is it possible to access filename from query?

It looks like the files from AACT can be pipe delimited or tab separated. If that’s accurate and if you are able to “partition” the files into separate directories, you should be able to see the directory names (as dir0, dir1… etc) when you promote/format the upper level directory. Like so:
