  fileop [-f X ]|[-l # -u #] [-s Y] [-t] [-v] [-e] [-b] [-w] [-h] [-d]
       -f # Force factor. X^3 files will be created and removed.
       -l # Lower limit on the value of the Force factor.
       -u # Upper limit on the value of the Force factor.
       -s # Optional. Sets filesize for the create/write.
       -t # Verbose output option.
       -v # Version information.
       -e # Excel importable format.
       -b Output best case
       -w Output worst case
       -h Help text
       -d <dir> specify starting directory.
 *
 * X is a force factor. The total number of files will
 *   be X * X * X   ( X ^ 3 )
 *   The structure of the file tree is:
 *   X number of Level 1 directorys, with X number of
 *   level 2 directories, with X number of files in each
 *   of the level 2 directories.
 *
 *   Example:  fileop 2
 *
 *           dir_1                        dir_2
 *          /     \                      /     \
 *    sdir_1       sdir_2          sdir_1       sdir_2
 *    /     \     /     \          /     \      /     \
 * file_1 file_2 file_1 file_2   file_1 file_2 file_1 file_2
 *
 * Each file will be created, and then 1 byte is written to the file.
