I'd like to suggest adding a mode that combines the path and filenames as one string for most operations such as viewing, filtering, searching and tagging. Essentially it would be a combination of the data in the directory and file windows, with one file per line. This would allow filters that contained criteria in both the path and filename at the same time, for example "M:\*\In\Control\160611.csv". It would also be easier to see the path of each file when viewing a Global list. Sorting by path may be more intuitive as well.
