This method behaves very similarly to the SaveAs method but it
ensures that MacBinary format files are saved in Services For
Macintosh (SFM) format. This method uses an
unmanaged call to the Windows API so you must ensure that you have
permission to call unmanaged code.
If you save to an NTFS volume and the upload was in MacBinary
format then the the complete file will be saved with data fork,
resource fork and other file information completely intact. Windows
users will see only the data fork but Macintosh users accessing the
volume using Services for Macintosh (SFM) will see the complete
file as uploaded from the client browser.
If you wish to maintain the Macintosh filename you should save
the file using the WinSafeFileName as a base filename.
Whether the path is treated as a virtual path or an absolute
path is determined by the standard ABCUpload path
Whether other files are automatically overwritten is determined
by the Upload Overwrite property.
