Recursively finding only directories with FileUtils.listFiles

Question

I want to collect a list of all files under a directory, in particular including subdirectories. I like not doing things myself, so I\'m using FileUtils.listF

Answer 1

An old answer but this works for me:

FileUtils.listFilesAndDirs(new File(dir), TrueFileFilter.INSTANCE, DirectoryFileFilter.DIRECTORY);

shows both:

I use:

FileUtils.listFilesAndDirs(new File(dir), new NotFileFilter(TrueFileFilter.INSTANCE), DirectoryFileFilter.DIRECTORY)

Only shows directories and not files...
