File Management API

[diskord]

Does anybody know if there is either a good way in Win32 to remove a directory on the hard drive in one go if it contains other directory's & files, or, if there is a nice API out there which has good file management.

Any help would be appreciated, thanks

#include <windows.h>
#include <stdio.h>

BOOL DelTree ( char *Dir )
{
  DWORD Attr = GetFileAttributes ( Dir );

  if ( Attr == 0xffffffff )
     { return FALSE; }

  if ( !(Attr & FILE_ATTRIBUTE_DIRECTORY )) // Not a directory
     { SetLastError ( 3 );
       return FALSE; }

  WIN32_FIND_DATA wfd;
  char DirContents[MAX_PATH];

  strcpy ( DirContents, Dir   );
  strcat ( DirContents, &quot;\\*&quot; );

  HANDLE FH = FindFirstFile ( DirContents, &wfd );

  if ( FH != INVALID_HANDLE_VALUE )
     {
       do {
            strcpy ( DirContents, Dir );
            strcat ( DirContents, &quot;\\&quot; );
            strcat ( DirContents, wfd.cFileName );

            if ( wfd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY )
               {
                 if ( strcmp ( wfd.cFileName, &quot;.&quot;  ) != 0 &&
                      strcmp ( wfd.cFileName, &quot;..&quot; ) != 0    )
                    { if ( !DelTree ( DirContents ))
                         { FindClose ( FH );

  return RemoveDirectory ( Dir ); }
