Question

In Win32 API, there is CopyFile that literally copies a file. However, this API doesn’t create folders. For example, I’d like to copy C:\Data\output.txt to D:\Temp\Data\output.txt. But, the target folders, D:\Temp and D:\Temp\Data‘, do not exist. In this case, this API just fails.

Is there a handy API that can automatically and recursively create directory structure on copy? Definitely, I can make such function, but I expect someone already made the function.

SHFileOperation should do the trick. From MSDN:

Copy and Move operations can specify
destination directories that do not
exist. In those cases, the system
attempts to create them and normally
displays a dialog box to ask the user
if they want to create the new
directory. To suppress this dialog box
and have the directories created
silently, set the FOF_NOCONFIRMMKDIR
flag in fFlags.
