I did look it up, even before the first time you told me too. But I am still having trouble figuring it out. How do I used the array listFiles returns?

Also note that directories will also be included and can be discerned with file.isDirectory(). If you need to include file counts from subdirectories, you'll need to do the recursion yourself.

I am writing a program that should return the number of files in a user specified directory. I have a sample program that returns the size of a directory. How would I go about changing it to return the number of files? (You referred to it in this post.)

        //Store the total size of all files
        long size = 0;

        if(file.isDirectory()){
            //All files and subdirectories
            File[] files = file.listFiles();
            for (int i = 0; i < files.length; i++){
                //Recursive call
                size += getSize(files[i]);
            }
        }
        //Base case
        else{
            size += file.length();
        }

        return size;
    }

}

You can count them recursively the same way you determined the total size. I assume you don't want to include directories in that count.
