| Description |
The GetDirectories method returns an array of strings that hold the absolute paths of the sub-directories of the specified PathString. Optionally, this list may be limited by the Filter string.
The array size is dynamically set by this method.
This filter string may contain valid directory name characters, but may not have consecutive . characters. Use * wildcard to represent a sequence of 0 or more characters, and ? to represent a single character.

| | Notes | Static methods are not methods of an object - they are simply class functions or procedures available at any time.
