ncfc is a tool for finding directories with large numbers of descendent files.
I found myself struggling to use rsync(1) to copy a directory that had, due
to some poor planning and the design choices of the build system,
several million symlinks contained (deep) within it. This makes rsync rather
unhappy, and produces a lot of overhead with merely the list of updated files
(on initial sync, over 500 MB!), and so I went on a hunt to see where all these
files were coming from. Even with some convenience wrapper functions, doing a
find <directory> | wc -l on every directory in the current level, followed by
moving one layer lower, and repeating ad nauseam, was an unpleasant experience.
Many people go through a similar process with du(1) when trying to find large
files until they discover ncdu(1). Just as ncdu is "ncurses
du", so ncfc is "ncurses file count" (or "ncurses file
| wc", if you prefer).
