Change Log:
  • 3.7.0 Updated not to use a regular expression for the skip list

Copies a directory from one location to another via the WordPress Filesystem Abstraction.

Assumes that WP_Filesystem() has already been called and setup.

This is a temporary function for the 3.1 -> 3.2 upgrade, as well as for those upgrading to 3.7+
