File/Folder Copying

Hello everybody,

The goal of my program is to make a back-up utility which will copy some files to a temporary folder, zip them and delete the folder again. However, there two categories of files: a few fixed configurationfiles and a lot of data files. These datafiles can are stored in folders (with possibly some subfolders). The first category I can copy with the CopyFile command without any problems. This command wasn't possible to use for the second category because I can't use wildcards with this command.
So, I tried with the CopyFolder-command but this didn't work. When I look at it in the help, I see that it's related to IMAPISupport. Do I have to include an additional header or so before I can use this function?
I am using VC4.2.
At the end I will include my code and the recieved errors.

Thanks in advance,
Johan
