DeleteFile

I love M$ for this, it's so intuitive.

[roger5089]

also _wremove()

Kuphryn

that's best one

if( remove( "test.dat" ) == -1 )
perror( "Could not delete 'test.dat'" );
else
printf( "Deleted 'test.dat'\n" );

system("pause");

Well, I would still go for DeleteFile, since it's underlaying WinAPI.

I would use ::SHFileOperation() with FO_DELETE since DeleteFile()/ remove() would fail to delete read only file.

  SHFILEOPSTRUCT fo={0};
  fo.wFunc  = FO_DELETE;
  fo.pFrom  = "C:\\delme.txt";  
  fo.fFlags = FOF_NOCONFIRMATION|FOF_SILENT;

  ::SHFileOperation(&fo);

Cheers

No, It is the same as DeleteFile. Just look at the source code:

void PASCAL CFile::Remove(LPCTSTR lpszFileName)
{
	if (!::DeleteFile((LPTSTR)lpszFileName))
		CFileException::ThrowOsError((LONG)::GetLastError());
}
