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

I avoid the Java IO libraries in most of my non-trivial applications, preferring Commons VFS instead. I believe a call to this method with the appropriate params will accomplish your goal, but I'll grant its a long way to go for the functionality.

Specifically, this code will do what you want:

    FileObject[] files = fileObject.findFiles(new FileSelector() {
        public boolean includeFile(FileSelectInfo fileInfo)  {
            return fileInfo.getFile().getType() == FileType.FOLDER; }

        public boolean traverseDescendents(FileSelectInfo fileInfo) {
            return true;
        }
    });

where fileObject is an instance of FileObject.
