#include <windows.h>

int main(void)


LPCWSTR szDirPath = L"c:\\testdir";


LPCWSTR fname = L"c:\\testdir\\testfile.txt";


// Create a new directory.

if(!CreateDirectory(szDirPath, NULL))

printf("\nCouldn't create %S directory.\n", szDirPath);


printf("\n%S directory successfully created.\n", szDirPath);


// Create a file

hFile = CreateFile(fname, //file to be opened

GENERIC_READ, //open for writing

FILE_SHARE_READ, //share for writing

NULL, //default security

CREATE_ALWAYS, //create new file only


//archive and impersonate client

NULL); //no attribute template


// Check the handle, then open...


printf("\nCould not open %S file, error %d)\n", fname, GetLastError());



printf("\n%S file HANDLE is OK!\n", fname);

printf("\n%S opened successfully!\n", fname);



// Close the handle...

if(CloseHandle(hFile) != 0)

printf("\nCloseHandle() for %S file succeeded!\n", fname);


printf("\nCloseHandle() for %S file failed!\n", fname);


if(DeleteFile(fname) != 0)

printf("\n%S file successfully deleted!\n", fname);


printf("\n%S file deletion failed!\n", fname);


// Delete the directory...

if(RemoveDirectory(szDirPath) != 0)

printf("\n%S directory successfully deleted.\n", szDirPath);


printf("\n%S directory deletion failed.\n", szDirPath);

return 0;



Output example:


c:\testdir directory successfully created.

c:\testdir\testfile.txt file HANDLE is OK!

c:\testdir\testfile.txt opened successfully!

CloseHandle() for c:\testdir\testfile.txt file succeeded!

c:\testdir\testfile.txt file successfully deleted!

c:\testdir directory successfully deleted.
