// A sample program to illustrate how to use Project Explore from Origin C by

// PEDir:	List pages and folders
// PEMD:	Creat a new folder
// PERD:	Remove an existing folder
// PECD:	Change the current path(folder)
// PEMV:	Move a page or subfolder in current folder to another folder
// PESCH:	find a page in current folder and subfolder, and printf full path of location if find.
// PEREN:	Rename the Page or subfoler
