IRootStorage - Compound File
Implementation
OLE s compound file implementation of IRootStorage
provides a way to support saving files in low-memory or low disk-space
situations. For information on how this interface behaves, see IRootStorage.
When to Use
Use the
system-supplied implementation of IRootStorage only to support saving
files under low memory conditions.
Remarks
It is
possible to call OLE s implementation of IRootStorage::SwitchToFile
to do a normal Save As operation to
another file.
Applications that do so, however, may not be compatible with future generations
of OLE storage. To avoid this possibility, applications performaing a Save As operation
should manually create the second docfile and invoke
IStorage::CopyTo. IRootStorage::SwitchToFile should beused only in
emergency (low memory or disk space) situations.
