Hi!
you can use
access C runtime, for example:
     if (access(lpszFileName, 00) != -1)
          {
// file exist
}

Use:

CFile::GetStatus()

static BOOL PASCAL GetStatus( LPCTSTR lpszFileName, CFileStatus& rStatus );

Just pass it the name of the file and a reference to a CFileStatus struct.  If the call fails it's due to the the file not being there or not being accessible to you.

The 'official' Win32 way would be to

if ( -1 == GetFileAttributes ( "drive:\\path\\file.ext"))
{
 // doesn't exist
}
else
{
 // exists
}

Note that this way doesn't require to open the file.

Well, this is the MFC topic area so I'd say the "official" MFC method is to use CFile::GetStatus().  ;-)

But either will get you the same result....
