Because my friend and I wanted to do a little benchmarking to compare the
speed of a bash script and this C script. The bash one is about 100 times
slower, at least ! But, we didn't look too smart after it created over 10,000
subdirectories and that we didn't know how we were going to get rid of them.

Thank you, there's a C one from the other person that is a little faster than
the bash, but I never thought of this method.
