Copying and Moving Folders

How could we copy or move contents of a whole folder to a different location? The following algorithm may be used:

Determine ENTRYID of source folder.
Open new parent folder.
Use its IMAPIFolder::CopyFolder method supplying source folder entry ID as a parameter.

The only difference between copying and moving would be usage of FOLDER_MOVE flag in the last parameter of the CopyFolder function. The code below (Folders/CopyFolder) copies the contents of the Drafts folder into a new folder named "Copy of Drafts". You can modify this code by adding FOLDER_MOVE flag to make this sample move this folder instead of copying.

#include <afxwin.h>
#include <edk.h>

int main()
{
    /*
     * Algorithm:
     * 1. Logon to MAPI and open message store.
     * 2. Locate source folder.
     * 3. Open the parent of the destination folder.
     * 4. Call IMAPIFolder::CopyFolder

    // Change if necessary
    char * pszSourceFolder = "@PR_IPM_SUBTREE_ENTRYID\\Drafts";
    char * pszNewParentFolder = "@PR_IPM_SUBTREE_ENTRYID";
