IFileDocument.SaveAs Method

Saves the file with a different name. The Save As command does not drop a document's operation history. Passing the name of an NTFS alternate data stream to this method is an error and leads to undefined behavior.

To save a document to alternate data stream, first create a stream (this function is outside the scope of this library), open the File Document Object for created stream and use the Copy and Paste methods to copy the contents. Then call the created object's Save method to apply changes.
