This class is now deprecated in favour of RangedDirectoryIterator.
Searches through the files in a directory, returning each file that is found.
A DirectoryIterator will search through a directory and its subdirectories using
a wildcard filepattern match.
If you may be scanning a large number of files, it's usually smarter to use this
class than File::findChildFiles() because it allows you to stop at any time, rather
than having to wait for the entire scan to finish before getting the results.
Please note that the order in which files are returned is completely undefined!
They'll arrive in whatever order the underlying OS calls provide them, which will
depend on the filesystem and other factors. If you need a sorted list, you'll need
to manually sort them using your preferred comparator after collecting the list.
It also provides an estimate of its progress, using a (highly inaccurate!) algorithm.

prevent it being overwritten

have disappeared. If it fails, the temporary file will probably still exist,
