* This depends on:
* (1) pTo points to the name of an existing directory;
* (2) the flag FOF_MULTIDESTFILES is present;
* (3) whether pFrom point to multiple filenames.
*
* Some experiments:
*
* destisdir 1 1 1 1 0 0 0 0
* FOF_MULTIDESTFILES 1 1 0 0 1 1 0 0
* multiple from filenames 1 0 1 0 1 0 1 0

* copy files to dir 1 0 1 1 0 0 1 0
* create dir 0 0 0 0 0 0 1 0
