FTS interface
The fts interface from BSD is simpler to use than Python's os.walk for most cases. It's also more flexible, it provides more information, and it requires far fewer calls to stat, making it inherently faster (around 3x-7x on tests on different platforms) for many use cases.
Interface
The fts module's interface is a Pythonified version of the BSD (and probably future POSIX) fts API.
Changes from the BSD interface are:
fts.open in place of fts_open. Constants, functions, and struct members lose the FTS_ and fts_ prefixes. Failures raise OSError. (Error reading directories, etc., are generally not failures, and are returned in the error field of an FTSENT.) All other functions become methods of the FTS object (e.g., f.read() instead of fts_read(f)).
