I may be blind, but I don't seehow that technique can "reclaim" any space.
all it does is fill up all the space not allocated to other files by creating
one large file that occupies all otherwise unused disk space.
presumably you'll delete that file once it is created, but you won't have
any more free disk space than you had before. the only difference will be
that that unused space will then be filled with zeroes.
what are you actually wanting to do here?
