In addition, if you're doing this for a large number of directories the
additional overhead of the SYSTEM call, even with the noxwait and
noxsync options set, is a huge burden compared with using the Windows
API approach.
Although I haven't any figures to hand, ISTR when I tested the two
approaches recently, creating over 10000 subdirectories in about 500
directories, the API method was several orders of magnitude faster.
