Being a huge directory set the traversal is taking days to do a
traversal.
Sometimes it is the case there is a crash because of a programming
error.
As each directory is processed the name of the directory is written to
a file
I want to be able to restart the walk from the directory where it
crashed.

Is this possible?

I would write my own walker which sorts the directory entries it finds
before walking them and can skip the entries until it gets to the
desired starting path, eg if I want to start at "/foo/bar" then skip
over the entries in the root directory which start with a name before
"foo" and the entries in the subdirectory "/foo" which start with a name
before "bar".
