Detect files?

Is there a way to find out how many files are in a folder and save it to a variable?

Not very clean or efficient, but short:

function System.numFiles&#40;dir&#41;
  -- - 2 to not count . and .. &#40;remove if you want to count them&#41;
  return table.getn&#40;System.listDirectory&#40;dir&#41;&#41; - 2
end

If you don't want to count subfolders as files you'll have to do a bit more work ;)

files = System.numFiles("/dir/dir/") , where "dir" is a directory, isnt working

table.getn(System.listDirectory())

If you're not in the root directory you'll get to extra files.
