Can IMAPI2 burn files with the size > 4Gb?

Question

IMAPI2 interface IFileSystem uses COM IStream interfaces to represent file data. There is AddTree method that adds specified directory contents to IFileSystem. So AddTree must create IStream's in the process. I wonder what implementation of IStream it uses? If it uses the standard OLE implementation than we have a nasty problem because OLE streams doesn't support files bigger than 4Gb.

Can anyone shed some light on this issue?

Answer 1

Apparently AddTree uses SHCreateStreamOnFileEx which apparently supports large files. I'll accept my answer when I'll check it.
